Hi,

After creating a rootfs/container with mkosi with:

  # mkosi -d opensuse -r current -t directory -o rootfs

I ended up with os-release looking weird:

 # cat rootfs/etc/os-release 
 NAME=Dummy
 ID_LIKE="suse"

Apparently it's due to the fact that dummy-release package was selected during
the installation, which is not supposed to happen since this package should not
be installable outside the build system.

According to Dominique, this is an old bug that was fixed in Factory back in
2019 but is still present in SLE. The fix consisted in adding "Requires:
this-is-only-for-build-envs" in the specfile.
