Title:
  fstrim.timer always triggers at 00:00, use RandomizedDelaySec

Status in util-linux package in Ubuntu:
  Confirmed

Bug description:
  fstrim.timer always triggers at 00:00:

  $ systemctl list-timers fstrim.timer
  NEXT                          LEFT        LAST

days ago fstrim.timer fstrim.service

  1 timers listed.
  Pass --all to see loaded but inactive timers, too.

  This can be an issue if concurrent runs cause increased I/O load on
  multiple servers which are part of the same system architecture (I
  have no hard facts via monitoring on this, but assume this can be an
  issue).

  /lib/systemd/system/fstrim.timer does not try to randomize the start time.
  systemd.timer(5) suggests that RandomizedDelaySec can be used to introduce 
variable start times, allowing for balancing out the (suspected increased) I/O 
load across multiple systems.
