After building an initrd with Dracut with systemd (which pulls in tpm2-tss module), prior to switching sysroot, these non-fatal errors will appear: /usr/lib/tmpfiles.d/tpm2-tss-fapi.conf:2: Failed to resolve user 'tss': No such process /usr/lib/tmpfiles.d/tpm2-tss-fapi.conf:4: Failed to resolve user 'tss': No such process /usr/lib/tmpfiles.d/tpm2-tss-fapi.conf:6: Failed to resolve group 'tss': No such process /usr/lib/tmpfiles.d/tpm2-tss-fapi.conf:7: Failed to resolve group 'tss': No such process /usr/lib/udev/rules.d/60-tpm-udev.rules:3 Unknown user 'tss', ignoring. /usr/lib/udev/rules.d/60-tpm-udev.rules:4 Unknown group 'tss', ignoring. The tpm2-tss module does attempt to create at least the tss user via a file in sysusers.d: https://github.com/dracutdevs/dracut/blob/master/modules.d/91tpm2-tss/module-setup.sh#L35C21-L35C35 The problem is this file tpm2-tss.conf does not exist on Gentoo machines. It is normally installed by tpm2-tss but we do not because we have acct-user/tss and the group packages. I think the best solution to send a patch upstream so that the acct-user/acct-group files are considered as well as the standard file.
