Should I at least raise a feature request in GitHub?Trust me when I say you don't want a PR from me. I've been poking around mkosi and my Python skills are a much better fit over there than my lack of C skills.

I was hoping that both root and /usr get mounted as appropriate. I can confirm when using 'systemd-dissect /dev/sda' that there is a designated /usr partition with a label that isn't '_empty' and for the correct architecture. Either I've done something wrong and need help or systemd-gpt-auto-generator is working correctly and I'm wrong. All feedback is appreciated.This functionality is still missing in systemd-gpt-generator currently. Would love to review/merge a patch that fills in the gap. (In my own usecase I always used usrhash= on the kernel cmdline, to pin a specific /usr/ fs to a specific kernel, thus /usr/ auto discovery was never needed, but we should definitely support that too) Lennart -- Lennart Poettering, Berlin
