it behoves one to check and make sure trim is supported or not on ones ssd drive before enabling it.

Code:

harry@harry-Latitude-XT2:~$ sudo hdparm -I /dev/sda | grep "TRIM supported"
[sudo] password for harry:
       *    Data Set Management TRIM supported (limit 1 block)
harry@harry-Latitude-XT2:~$

I only mention this because my zif ssd drive on my atom netbook cannot support enabling trim on it.
Enabling trim makes that zif ssd drive unbootable. I have fixed it using live tools. Restore backup fstab and rc.local files. Move /fstrim back into /cron/weekly. Then my atom netbook would boot ok again then.

Lastly. Anymore. I trim my ssd manually instead of on every boot.

Code:

harry@harry-Latitude-XT2:~$ sudo fstrim -v /
[sudo] password for harry:
/: 2872553472 bytes were trimmed
harry@harry-Latitude-XT2:~$ sudo fstrim -v /home
/home: 120884785152 bytes were trimmed
harry@harry-Latitude-XT2:~$

leaving my boot and cron jobs alone.
