Setting loginuid for a process starting at boot

[Maupertuis Philippe]

Thank you so much for your very valuable answers.
After playing around, I found that the assignment of loginuid  produces a login type message (I could have guess)

Where can I find the description and the trigger of all messages types if such a documentation exists ?

Both are auditable events as required by common criteria. Changes to auditing must produce an event as well as the assignment of loginuids. This is automatic and not caused by a rule.

Changes to audit state are auditable events. You can test this yourself with auditctl and ausearch.

yes.

You can write a utility using the auparse library to do anything you want it
to do.

The aulastlog program is probably a decent starting point to create something
like this. Instead of keeping uid, you'd be keeping pids and some attributes
of them. My guess is that you'll have long running processes that are not in
the logs and you'll have some unknowns.
