Kernel-install-for-dracut / hooks vs systemd-boot loader title/sortkey

General system Kernel, boot, graphics & hardware

I’ve been testing EOS, and I have a KVM with 3 EOS installs on one disk.

Systemd-boot is using EndeavourOS as the title for each loader entry, and sort-key prefix.

With one EOS install on a disk that is fine. With 3 and 3 fallback all with the same base name it is a bit unwieldy.

I have /etc/kernel/entry-token setup, and that is working for the /efi/entry-token path for linux and initrds, and this has the nice property that the machine-id string disappears from my /efi, replaced by my install instance name/hostname from the entry-token.

For multiple installs I think entry-token would be a better title and sort-key prefix, and I already have it in the file system, and kernel-install uses it, but seems like /etc/kernel/install.d/90-loaderentry.install would need to change to accommodate that, and maybe kernel-install too, and maybe 90*fallback too, I haven’t perused sort-key much as yet.

@dalto as the owner of the package is that interesting to you, me hacking the package a bit and sending you a PR, for a what is I’m sure a very edge case?

The other way I thought was maybe just creating a local 91-loaderentry-hack.install and hacking the already built entries with sed -i? Can be simple, and local system only hack.

Does anyone have any other ideas how to accomplish this with minimal impact and maximum supportability. I generally like to just drop files in place via ansible, so the 91 option appeals.

I looked at the EOS wiki and Arch wiki, and found nothing at this level of detail

I think all that would need to change is /etc/kernel/install.d/90-loaderentry.install and you would need to also copy 90-loaderentry-fallback.install there and change it as well.

For most installs, putting Entry-token into the name would be a nuisance as it is generally the machine-id unless you have specifically set it to something else. I would need to think about it when I am more awake though.

I thought I would have to hack 90 fallback too.

I have culled the machine id from the cmdline lines, root= is sufficient for me to identify with ‘e’, and one machine-id blurs into another when they are random hex.

No hurry, I’m still leaning towards just making my own 91 to post hack the install, unless you think this would be more generally useful.
