Have you seen the cron '@reboot' facility? This will run whatever command
you give it when Linux starts.
You might want to give it a script which checks for the existence of some
flag to tell it whether it wqants to run fstrim or not, depending on
whether fstrim got run by a regular scheduled cronjob (which could set
aforesaid flag).

Hi there,
I believe a while back I was talking about TRIM here, more specifically
about it not running automatically on my systems, and I think someone
recommended I enable fstrim.service with systemd.
I finally got around to that, only to find that it was already enabled,
and apparently not doing anything. As I don't leave my systems on 24/7,
is it safe to assume that the timer isn't firing when the system is
booted up later, after the configured time for TRIM has passed?
If so, does anyone know how to configure a task like this to run when
scheduled, or alternatively when the system is next booted up in the
case that the event was missed?
I know CRON can't do this, and I assumed the point of using systemd
timers was that they could do this, but alas perhaps not. I assume there
must be a standard way to do this, because it seems like a rather big
omission, considering that other commercial operating systems Who Must
Not Be Named (TM) seem to have had this feature for a while.
Any ideas?

Cheers all,
I have added:
7 50 fstrim -av
To /etc/anacrontab. Hopefully that'll do it.
This should really be in there for most distributions by default IMO.
