Public bug reported:
After upgrading from Ubuntu 25.04 plucky to 25.10 questing there are
several errors shown during every boot process:
systemd-tmpfiles[305]: Failed to parse ACL "default:group:tss:rwx", ignoring:
No such file or directory
systemd-tmpfiles[305]: Failed to parse ACL "default:group:tss:rwx", ignoring:

systemd-udevd[430]: /usr/lib/udev/rules.d/60-tpm-udev.rules:4 Unknown group
'tss', ignoring.
I've checked that both "tss" user and group exists.
I think that these errors are caused as a result of "initramfs-tools"
being replaced by "dracut". Probably old "initramfs-tools" didn't insert
the tpm udev and tmpfiles rules in the initramfs so there were no
problems. Seems that new "dracut" is inserting these rules/files in
initramfs but it's not inserting the "tss" user and group needed for
these to work.
Additional info:
tmpfiles rules: /usr/lib/tmpfiles.d/tpm2-tss-fapi.conf
udev rules: /usr/lib/udev/rules.d/60-tpm-udev.rules
