fstrim and SSDs and cron; was: Re: cron-service

[Danny Milosavljevic]

Hi Ludo,

thanks. 

I can confirm that this works!

I'm using it to regularily call fstrim (one has to regularily call fstrim on 
SSDs) so the mcron behaviour of, if an appointment was missed, doing it at the 
first next availability is good for regularity. The man page says that trimming 
once a week is good.

Longer term maybe there should be a way of specifying that a filesystem should 
be trimmed in a "file-system" specification. Note that fstrim expects the 
filesystem to be mounted for it to work.
