Description

https://github.com/intel/dffml/discussions/1406#discussioncomment-3729256

A

Okay, so I also remembered okay. I also remembered that we're going to need uh boot control, so uh we should modify our.

A

uh We should grab.

A

For whatever provides it right, so maybe we should go hgs right and check out root control.

A

So let's see no packages found.

A

Okay, so let's see this may be an Arch Linux or what was it called.

B

B

A

A

um Average, throw this under um mu all right: okay, so bootloader.

A

Close the SSI service ones now.

C

Okay, what is this okay.

A

We don't need that right now,.

C

Let me see: what's in there,.

A

First, yeah, okay, so there's proc dances see we ended up having to do that too.

A

I, don't think we did everything. Let's.

C

C

Let's reference it anyways foreign.

B

B

A

A

Okay- let's just go here to clean up some stuff here, so we don't want that. Okay, so here we want to go back to the installation guide. Okay, did we do that already loader Okay, so.

B

B

C

C

A

Example, layouts from disk partitioning, that's helpful too.

A

Basically, two things primarily that we referenced there um and then the rest of it will just be basically like a like on target um okay. So then we wanted okay, maybe no I, don't think we wanted to download. So that's just what we're using to boot again, we've got the net boot link. Did we get the net boot link?

A

Okay, there is the Nepal link.

A

A

I lost I hate it when I lose stuff during this time to find a better system. Okay. So then we also had.

A

This was helpful.

A

For what was this helpful for Okay? So.

B

B

B

A

What else here.

A

We saw my root assessment. We ran into this all.

B

A

Boot control, yes,.

A

We're trying to configure boot control right, okay, so we need to configure control. We need to configure this by.

A

And then where's that example control file.

A

Or no, this is just going to create the EFI step directly as well. Yeah, okay! So basically, oh type, two! Okay! So that's that's what we're doing? Okay, so yeah, there's two versions. So if you go type, two automatic boot assessment, okay, so move control, and then what was this? What did we run for boot control?

A

Where was that uh we were in the okay? We were in the VM.

A

A

Okay- and we had to do that- find replace on the truck okay, so the docker file here. um Okay, so do you have download okay, honestly I think we might just do a dnf install on rocket.

A

Because it doesn't need to be in the system because we're going to set up this update or well yeah, we'll we'll put it in but we'll we'll put it in the system. Okay,.

A

A

Okay, so what was that modification we made.

C

A

Tempter had a read link on it, so this read-only okay, so this line that says read-only tempter basically grab this line, replace that make it say this right: okay,.

A

Okay, yeah: that's what we want. Okay, so and then this kernel version here comes from.

A

Okay, this kernel version comes from.

A

This comes from that uh lib modules directory.

A

Right, okay, so there it is Loop.

B

Modules: okay,.

A

And then we basically just pass that here.

A

Right at least that's Theory,.

A

Okay, so time through temp, okay, so run draw cut so fixed draw cut figure out what kernel version we're on okay.

A

Next track or no, we don't need to do that on this one because we're in fedora okay, so it doesn't matter.

A

But once we're here we need to do it.

A

Let's extract that because there it is now read blank: oh okay,.

A

Okay or because we could not find what package on we'll see, provides read like okay, big Straw Hat because or patch patch draw cut, because we could not find what package on Wolfie provides. Read: link; okay, that's perfect! Okay, uh although we're not sure I'm, not sure if we're gonna have SED on this. So let's just add: SED, um okay, yeah and actually let's this. This is going to be our nice handy dandy list of all. But this is the wish list right here, so bash SCD, mux um or well.

A

They they may not happen too much. So it's just too bad for anything else. Okay! So and then oh yeah, we're gonna. Do one uh user such.

C

A

Words fastest add juicy dishes which rash.

C

A

A

A

A

A

Find the kernel version and live modules. Okay, but this is the thing is that it was extracted. Okay, so kernel core okay. So what do we want? We want RPM file, so we want RPM file to list because it's not in lib modules um because there's nothing in there we're in a container right now. This is the dnf within the container, so it probably or who knows what it has right, but it's not what we want. So we want what they are. Excuse me.

A

We want what the RPM is going to install right, so that would be kernel or whatever right so start. um So we'll just do kernel core star okay, so it should list out these files and it does that. What are we going to be looking for.

A

Okay, okay, so we are in what are we in right now: directable container Okay? So let's.

C

A

Actually that takes us to an important point which we definitely need and then we're going to install Alice. Okay, so draw cut okay, so urify. So we generate to you if I, um okay and where is draw Cuts output to foreign.

A

Through control, oh yeah, that's right, the the Etsy environment. We need that as well. Okay, so control, okay, great.

A

Esp pad so that was our magic command there through control.

A

This has to be run um and we were running this from okay yeah. So let me throw that on there as well right, so we booted into the arch ISO right, so we net booted, okay, so we net boot into the arch ISO. We run boot control, let's jump up to our installation.

A

Okay, I know I'm, just like I know: okay, it's unless we write this down so um so, no boo, um okay and then okay, so uh our script formats or, let's see.

A

A

A

um So decentralize.sh.

A

So practice uh creates okay.

B

B

Disk by default.

A

And formats are additions.

A

A

3Fi applications, okay,.

A

Okay, net boot Okay, so uh we download the pxe net boot image um and use it to boot to Arch Linux uh and.

A

Our Arch Linux five uh live image used, which is usually used.

A

Oh, it didn't scroll the resell, the scroll back, okay used.

A

Usually used for installing arsenaline X, but there's no reason, no reason we can't I. This is always my go-to if we're, if for any live media, um this is a good one. So, but there is no reason we can.

A

um We can't um use it to install this.

A

A

Foreign, okay,.

A

Did we say we were going to go downstairs.

A

Okay, so yeah so.

C

We get in and then we look at.

A

The show another bootloader install.

A

Okay so then, whatever to live.

B

A

Foreign, okay, so then okay, so what did we do? First? We went here and we mounted these right so mount um uh the. Where did we write this already.

C

That's where we wrote this somewhere, but that's okay,.

A

I took it oh Dev.

B

One number.

A

Mount I swear. We wrote this: where is this something else free to mount and then swap on two.

A

And root control install and then then it should automatically pick up. So we should we're going to use with drag height in the docker, build we're going to build that EFI step and it should build it right into Boot and wherever it's supposed to go and then we'll put in boot control we'll list out those files um after we do this right. So let's see.

A

C

Okay, so we should see.

A

Right so now we should see.

A

A

Okay, so that this looks like.

B

A

A

I have my bird okay, so we do the system debate because it's a boot manager, so if we put in right so what we found with what is it? Is it this one all right? You know.

A

A

Okay, so but okay, so this is, this is what we care about from that draw cut.

A

Okay, and what is this, this is okay, Mount, um cushions.

A

uh Partitions five, maybe uh media.

B

A

All right hacking, this thing back into these little sections.

A

Factory backer foreign.

A

Okay, so okay, so I'm presented Okay, so choose a country and a mirror uh uh then modify.

A

Right so we want to modify boot off options to add all right.

C

A

This is great foreign.

A

I love it when it's all text: okay,.

A

I'll get this: this is just wonderful.

A

And then we go down, let me say.

A

A

And then we're here: okay, we Mount the partitions okay. Now, oh, we had to set the path. That's right! Okay! So let's go back and add this to r.

A

Did we add anything else to the path? I? Think S, Pen.

A

All right, so we want a combination of the fedora and.

C

Fedora paths: okay, so.

A

So basically we'll do.

A

A

Okay, so then, let's add this so.

A

Okay, uh fedora stall path to um image environment.

A

A

To run echopathy um and we're gonna put it right so into build kernel.

B

A

Go kernel um and then VPC.

A

That means we're gonna have to create that. Okay, are we on the internet? Here we are.

B

A

Okay, I'm good Dash p, build kernel, Etsy so and then we put the path in there. So we Echo, Dash, e or Echo path equals.

A

And then quote and then path and then quote and then quote and then path actually and then later down here.

A

Okay and then later down here, we'll go and um match the path again.

C

C

A

Then here we'll just do colon path right and you should be happy with this. Then.

A

A

So create Etsy, create Etsy, environment path, open quote, dump the Fedora path and then um and then.

A

Okay add uh Wolfie pen.

A

Okay, first path, Edition second path: Edition, okay, and then we do the colon on that one. And then we put that in t.

A

Okay, we append this key okay and then oh and this one is actually going right into the environment and then.

A

Okay, great, so we get the environment from the first one, and then we put it into this one and then okay and I wonder I wonder if it will take on that and if not then yeah, we need to have a backup kind of plan which will be what did we have success with here.

A

Okay path: okay, so then,.

A

Okay and then it didn't want to execute bash for whatever reason right.

C

A

Don't know what was up with that.

C

Okay, fine round boot. Okay, thank you.

A

A

Let's put it here just in case okay, but that was once we were in the CH root right. So how did we get into the CH root? I think we lost it there unfortunately,.

A

It just keeps like vaulting that's right, um and why was that? Because we're running from this archlank slide.

C

Okay, I'm generally you'll find the French Linux slide from.

A

The end we've already installed the bootloader in the docker file.

B

A

Of that helped, oh we had to do that.

A

uh We had to do the MK dinner in order to get into the CH root.

A

A

All right and then I think it is.

A

Let's see show is Revenge zsh.

C

C

We'll try it okay.

A

So Ben sh finally got us in that looks like that works.

A

Let's see and then we hit that path.

A

Okay and then we have PS, so that's good and then we did add user.

A

A

A

A

Are we on the internet we're on the internet, okay, so.

A

All right, okay, I, like this.

A

Build it okay and then then.

B

C

What did I want.

A

um I wanted to run qmu Flash.

C

A

Okay, um let's see whatever the last Photoshop was just to open the shop.

A

And then does this have the curl it does, but the curl seems to be like not working quite right. So I think this is just going to drop us back to the EFI yeah. This is it's basically like nothing, okay, um so where's this okay. We want this right. Okay, so and it looks like our path, our path dumped worked there, okay, so that's useless.

A

A

Okay, so what do we want? We want a okay, so you're you're not gonna.

A

A

So we want to boot into, uh or we want to go into this right here, right that intermediate layer, oh you can't see where I'm pointing, but you can see where I'm selected, okay, so yeah we want to I, want to run RPM file right and I want to see what that listing looks like, because we have no idea what that listing looks like so, let's find out.

A

A

And then we'll know what to put on the other side of that corrupt call.

A

It's okay, great! So now what are we trying to do with this again.

A

Just barely made it all right, so system.map build config, hmac, okay, and what was it we wanted here. Kernel version. Okay, so we want lib modules right. So we want to know what is live modules. So, let's just do.

A

Loop modules, VM Linux right because.

A

All right, so this whatever we find here, so we want to do, grab for VM, Linux, right and then SCD and we're going to take off the lib modules right.

A

So we're just going to pick that off the front.

A

All right so we're going to take that off we're going to replace that there and we should end up with.

A

A

Okay and then we want to take off the VM minutes right, so we want to take what we're taking off this with the first Dash e to SED and we're taking out that with the second Dash e to CD right okay, so we just did our RPM file L get this listing right because we paused the container bill or well.

A

We failed to continue Village rate, and now we just like popped right in there we ran the command to see what the right filter and modification is to get the kernel version, and then we run dry cut on the Kernel version right. So now, because of our caching, we should jump right back in right around here: unterminated S, command rights, Network just right here, modifying.

A

So this is another slash.

A

A

B

A

A

Running in host only mode in a container Dash, okay, here, if I okay, so it didn't get the kernel version.

C

A

A

Oh, it says: P kernel version, okay,.

A

And then I'm now thinking.

A

Because it might need to be told to search in an alternate route.

A

Okay, let's see.

A

Through parameters and command line- okay, so that's interesting, so we can do.

C

C

C

Command line to this, so it would be really nice.

A

Okay, so that's right.

C

A

Okay, so we want that.

A

A

And then move on to those okay set our drivers, bad drivers course, drivers and mid drivers, file systems, K, monitor, forwarder, kernel, command line; okay, so great.

A

So this is great okay, so this we can do hard.

A

On and then you're gonna have a default one, something like console equals, TTY, s0 um console goes ttys0 and I, don't know how we would do the root stuff. I, don't know how we would do that.

A

How would we do that? We have another partition table I think we might have to redo this.

A

It will should at least drop us to a shell that we can ax like it should at least output stuff, and it may not know where to go from there.

A

Sister Sister directory: this is useful from a cross, compiler, okay, so CIS fruit. This is the sage key file used with SSH client module.

A

I wonder what that does I'm still.

B

Only with his need for recruiting the localhost.

A

Warning if you're true to another route other than the railroad device, your job has to have to provide a valid.

C

Etc FS tab, foreign.

A

Okay, that's probably something that we need.

A

A

And then I have this tab is build kernel, DTC, FS, tab, right, I, don't know if that's going to exist, probably not all right so.

B

B

B

Amount like above.

A

Mount to turn mouse, okay, so amount now device I'm Alpha in anywhere like this.

B

Okay, so we don't have it's an Ozium Edge is either compress.

A

No compressed key princessless modules.

A

Image draw cut will create an ureify executable which is executed. The area of five files, the default output file name is EFI. Efi Linux links, okay, so that should be good because we're Within um no we're not within we want it to go.

A

Okay, so Alpha file name is EFI.

A

C

Okay, so we probably need to then.

A

Copy um EF5 Linux through build kernel.

C

Boots, if analytics Okay, so okay.

C

B

So the ID is taken from build ID in OS release. Okay,.

A

No ufi, if I specifies the stepladder which will load the attached kernel. The default is live system, D, boot, okay, it says system reboot, okay, so if we have rocket installed, then it probably already has system bboot installed. It probably depends on that, so it might be if I would be.

A

Okay turn on image displays the current language to include within the AFI executable, okay, I, guess, okay, and this as I would assume. This is that this is okay. If that's special, oh, we can even put an image. Oh we should. We should note this for later. That's exciting!

A

That's very exciting!.

A

A

A

A

I love that I love that that's great okay, so, let's find out this works so.

A

Okay, so real path.

A

A

A

It's really insistent about that temperature.

A

You notice that it wasn't an option.

A

Okay, so you didn't like that either.

C

So, let's just make sure everybody's doing the right thing here.

A

Okay, so dry cut, so kernel command line is not there. So, what's up with that.

A

Okay, so command line okay, so we got the command line correct this time and so I'm looking down here. Okay, so cannot find build kernel, and this is Electronica track it in it.sh or you're running from get track.

A

Try passing L as an argument to use it.

B

C

A

I'm, almost thinking that we want to just install this.

A

All right, where are we installing truck.

A

Why don't we just do that and then it'll have it, and then we don't have to mess with this route.

B

A

B

You like that, all right.

A

A

I've been trying to do this for years. Obviously,.

A

I'm sick of it not working it's dumb. There should be like a really easy, automated way to create a VM image of basically whatever you want, because it's done that it doesn't I'm sure I mean maybe it does and I just don't know that, but until I do.

C

An excuse, my final quest, all right. Well, let's find out about BMP image formats.

A

Okay, so um invert, okay, okay,.

C

A

To BMP FFM code: okay, let's see if that works.

A

A

Let's try to grab a frame; okay, so object copy, okay, so running host. Only okay need object, copy to create UEFI, executable Okay, so dnf search object, copied.

A

No match is found.

C

What do you mean, how can you not find.

A

A

Okay, Fedora obj copy just um can we just do like.

A

A

Okay, PKG, this site is just just fantastic. Whoever makes this thank you.

A

A

That's like I eBay dinosaur and look it's fun too.

A

If I get it right, okay, wow.

A

It's just past the internet, okay,.

A

What is the following? Some of it seems to objects.

B

I'd recovery info.

A

Where is object copy the new EFI.

C

If I add the camera here, if I.

C

B

Okay: let's try to install hook update example.

C

A

Simple truck like caver s,.

A

Manager and we're not using that.

A

A

Okay, so this is good stuff.

A

Okay so I have to copy it to create.

A

Let's just look at it.

A

Okay, so what does it want? It's complaining about not having obj copy, okay command, B object, copy object, copy takes.

B

If object copy.

C

Okay, so object code.

C

Where is this from gnu.

A

Development tools. Okay, so is this like part of GCC, probably okay: let's install GCC.

A

A

Well, not ironically, but this is only like half a journey because well, at least as far as this present company is concerned, because this is uh not a EFI and that was part of the problem. I couldn't use it before.

A

B

B

C

Nobody's house.

A

Been utils, oh.

A

A

A

A

A

Let's see where's object, copy.

A

Oh I added it to here and add it to here too.

A

A

See if we had something declarative like this, you could actually do better caching and that's part of what we're trying to do. Oh, what was that realization? I had the other day. Oh oh, we want to do. Oh, no, oh yeah, earlier, okay, so we want to we'll have we need to create that we can really modify the data flow format and then within it, we're going to have within the seed inputs. Basically, we we we're, there's going to be some element within it.

A

That's like cash or something or just State, and then uh or timelines timelines, and then within timelines, we'll basically have a bunch of different nodes with different system contexts and then we'll have the graph between them.
