last time I looked auditd is started later than
systemd-sysusers. Hence not sure if sysusers would actually generate
audit messages that auditd could pick them up.

In general though: people who care about audit need to send us patches
for this, if this matters to them. I don't think anyone in systemd
upstream wil work on this on their own.
