From: Chen Qi <[email protected]> New systemd version (v258) introduces a new group, clock, to "enable applications like linuxptp to open clocks without root privileges".[1]
This results in warning at do_rootfs time: WARNING: Group clock has never been defined Add group clock with gid 81 to fix this issue. The wheel group's gid is 80, so 81 is chosen. Note that Debian rejects this patch because they're using sysusers to handle such groups, including 'clock', 'kvm', 'sgx', etc. We're not relying on sysusers, so we have to add a patch here. Below are more detailed reasons for why these groups (wheel, sgx, kvm, clock) need to be in base-passwd as oe-specific patches instead of being added via separate recipes: OE currently does not have a mechanism like systemd-sysusers that if a group has been added, the related configurations in separate packages do not have confliction. In OE, when multiple recipes need the same group, and these recipes do not necessarily have deps on each other, the current viable way to do this is to add that group to base-passwd. If things change in the future, which means significant change to our useradd related bbclasses, we might do similar as Debian. But before that, these groups need to remain in base-passwd.
