many: drop custom `distrodefs` and use images library #1066

mvo5 · 2025-10-06T07:44:48Z

Instead of having a separate implementation of the required
packages and the required lorax templates and similar we
now reuse the images data/distrodefs YAML so that all
the packages/definitions are maintained in a central place.

The one issue with this is that we no longer support the distrodefs
path concept:

var distroDefPaths = []string{
	"./data/defs",
	"./bib/data/defs",
	"/usr/share/bootc-image-builder/defs",
}

I'm 95% sure this is not used outside of testing but I wanted to call it out.

bib: add support for ID_LIKE when finding the distro YAML

This commit adds a fallback check when no direct match for
the distro ID from the bootc image is found. As long as
the bootc container sets a correct ID_LIKE we should
automatically have the same behavior as before when
we used symlinks as aliases.

If needed we might need to reintroduce an explicit
mapping like:

// mapping of distro IDs that are compatible with
var distroCompat = map[string]string{
        "almalinux":     "rhel",
        "aurora":        "fedora",
        "aurora-helium": "rhel",
        "bazzite":       "fedora",
        "bluefin":       "fedora",
        "heliumos":      "rhel",
        "rocky":         "rhel",
}

but lets hope we don't need this.

Note that these tests use the "real" distros.yaml from the images library
so make sure that if rhel-9 goes away the test is updated for rhel-XY
(only the version needs to change)

bib: use images library for shared bootc helpers

Reuse the helpers from the images library for to do:

labelForISO()
getDistroAndRunner()

This code moved into images as part of
osbuild/images#1906
and we can now reuse it here instead of duplicating it.

bib: drop no-longer used NullWorkload

Workloads are no longer used in the images library. This
NullWorkload is also no longer used so drop it.

This commits adds a new `bootc-rpm-installer` image type that contains only the rpm packages lists for now so that bootc-image-builder can use the images library to get what rpm package it needs to install to build a bootable ISO. The advantage is that we can retire the code in bib that the YAML loading for the pacakge lists and that we have one central location when we need to update image definitions. This is used by osbuild/bootc-image-builder#1066

LGTM, nice cleanup 👏

bib/cmd/bootc-image-builder/legacy_iso.go

 	if err != nil {
 		return nil, err
 	}
+	// XXX: or "bootc-legacy-installer"?


or bootc-package-installer based on "image mode" vs. "package mode"... I have no preference.

I prefer bootc-package-installer to bootc-rpm-installer. But I think legacy might be clearer here as something we want people to start moving away from.

Sorry, had to force push because of conflicts.

Also update for the renaming of image.NewAnacondaContainerInstaller to image.NewAnacondaContainerInstallerLegacy

Very cool. LGTM

I'm closing this in favor of osbuild/image-builder-cli#374 and #1157 - I think instead of this we can focus on making it a multicall binary directly. If it turns out to be too difficult/too much churn in a single go we can revisit/reopen this PR.
