Thank you for mentioning it. I have an SSD and occasionally have used
fstrim but wasn't aware of the fstrim.timer option.
And for those of you using SSDs, make sure you have a good backup plan
in place. SSDs are fast and a lot more reliable than they used to be.
However, when they die, they die suddenly and catastrophically--and
typically with no warning. I make it a rule to back up to magnetic media
frequently as I've been bitten by that issue often in the past.
