I don't mind about using a default schedule (but someone else might).
I think some distributions will be paranoia with this change and shiped
with disable by default in system config.

However, no `prefetch` in default schedule, please.
IIUC, this is a network operation, if someone is on the go and paying
their internet based on their traffic, this will be a disaster.

And I would say no incremental-repack, too.
Users don't want to a large operation of IO on some random time of the day,
be it when they open their PC in the morning, or when they want to close
their laptop to go home.

----------(Windows rant ahead)
I still remember those days that Windows 8 was introduced,
Back in that days, my computer still uses the old 7200rpm HDD.
I was super-angry that whenever Windows is started, it starts some IO
disk-caching, indexing that hung my computer for a good 10 minutes.
While that same computer can run Windows 7 and other OS fine.
I don't particularly care how much my computer is faster after that.
I want my computer usable at that time, instead of wasting a good 10
minutes on nothing.
---------(Windows rant end)

Either the users know what are they doing, or we don't do anything at
all. Let's them do it on their free time.

IOW, Please let users opt in instead of opt out of this features.
