Thanks a lot!

When a user loggs in, we resolve the name to UID. As the initial
logind binary was only used for login management, it was reasonable to
avoid starting up before the nss-user-lookup is initialized. Now that
systemd-logind provides other independent APIs, it might be ok to drop
that requirement again.
If the nss user lookup is not ready at the time someone logs in, we
will print a warning and skip tracking that session. Sounds fine to
me, but Lennart might have more comments.

Thanks
