What are these for?

[lee]

Hi,

what is auditd for?  The manpage doesn't tell me, and I can't find any
documentation about it telling me what the purpose is.  Is there
anything that speaks against disabling it?

Similar with mcelog:  What do I need that for?  And benefits from it?  I
can probably just disable it.

Do I need polkitd?  It doesn't make sense to me; if I want to do
something for which more permissions are required, I do it as root.  So
what's the benefit I would have from polkitd?


And I still don't see what makes the light of the onboard SATA
controllers flash all the time.  Why is it flashing though nothing
connected to the controllers is mounted?  See
