Somewhere between the upstream container
rockylinux/rockylinux:8.6.20220515 and the latest release, systemd
started to be pre-installed in the container.
With <= 20220515 installing the kernel-core package would end up
pulling in systemd. As part of the systemd package installation, the
/etc/machine-id file is created and populated.
The kernel package post-install steps install the kernel with
/bin/kernel-install; this is responsible for copying the kernel
binaries into /boot. It does this based on the machine-id, and it
seems its failure case with a blank machine-id is to simply skip
copying the kernels into /boot. To compound this problem, it seems
our bootloader installation doesn't notice that we don't have a kernel
installed, so we end up building an unbootable image.
Testing is/was showing us this; but as rocky is non-voting and this
occured at a random time (rather than in response to a dib change) I
think it slipped by us.
To work around this, create the machine-id early in the container. We
already have paths that remove the machine-id from final images.
