I’ve been able to follow most of the steps here without issue, except that I’m still not able to see any output from audit2allow -b. I updated my /sys/power/resume with the offset value for my /dev/nvme0n1p3 and I added the extra install_items line that underscoreDje mentioned. Finally, I also changed /etc/sysconfig/systemd to SELINUX=permissive and rebooted but still no dice.
The output of journalctl -k contains this message about lockdown:
Lockdown: systemd-logind: hibernation is restricted; see man kernel_lockdown.7
I do have secure boot enabled, but I’d like to keep it that way since this is a work machine. I know that’s a problem for hibernate after reading through the suggested kernel_lockdown.7 man page, but there’s an old comment in the gist linked in the post which says “there’s an effort to produce signed and verifiable hibernation images”. Since that was about Fedora 37, I was hoping there was some improvement on this situation. However, though I haven’t seen anyone outright say it, I am slowly putting it together that I may not be able to use hibernate at all because of secure boot.
Does that seem to be the case and should stop wasting my time on this?
