i somehow skipped the Callbacks part on that page, sorry.

here's some experimenting with Plymouth.SetUpdateStatusFunction, and was
wondering if i can get list of events that happened on last boot ? 
(so i could make this more generic and show the ghost when an event
comes that was not in last boot)

(does 3 boot runs, normal, fsck inteferring, after fsck)
