Or, maybe we can dnf installroot?

I made a quick and dirty version (gnome/amd only, bootc not working yet (.raw only)) if you are interested
https://github.com/jumpyvi/ultramarine-mk

looks good, doing a bit more than we probably would (usecase specific images aren't the ultramarine way) but a useful POC nonetheless

although it looks like there's an almalinux based dx version in there? what?

[jumpyvi]

@nothingneko

What would you remove exactly for it to be
more generally useful?

And the Alma stuff is leftover from my previous mkosi image, it shouldn't affect anything and will be removed eventually.

[nothingneko]

gaming and dx are the two things that we don't really do, nvidia image is fine, but i'd rather have users be able to install apps for any usecase than having some they are locked to

we're working on ways for users to get unconfined apps (particularly for devs)

also, not sure if the pkg is being pulled in but the tailscale repo is installed, also the ublue repo

[jumpyvi]

For unconfined apps, you could probably just build the "dx" profile with mkosi for exemple, and put the resulting rootfs diff inside a sysext or overlayfs.

Managing updates a version with overlay filesystem is pretty annoying, but GnomeOS managed to it, so it's probably possible.

Maybe it should be in another repo tho.

I don't know why you would have to rebuild the whole image from scratch with with mkosi when we can just layer the changes like we're doing already with the Containerfiles, would make it easier to build and maintain imo.

I recommend only building the base image with mkosi and layering changes on top like a typical OCI image
