So now I can do a fast reboot, halt the system, but - only using command
line. If I choose to shutdown the system through the Kicker menu, it still
takes almost two minutes.

I have disabled these plymouth-* services:


 but these ones remain enabled, as I am afraid to touch those:


Anyway, to disable something is just a workaround. Hope to find real
solution some time.
