I have just installed fresh from 9.1-RC3 ISO and cannot find a checkbox
to disable journaling or enable TRIM. Do I miss something here?
The only way I can find to customize is to go to the shell, which is an
option in bsdinstall partedit and then gpart and newfs from there. This
way I can align to 1 or 2 MB, enable TRIM and disable journaling, and
make use of all options someone desires.
Also I tried using the shell at the end of the install to disable
journaling, but this cannot be done since /mnt is busy.
Just rebooting to single user mode after the install and then tunefs -j
disable /dev/ada0p2 works for me.
Replace ada0 with the device your disk is on, p2 is the defalt partition
After a reboot then I just removed /.sujournal
Still I have send a pr with patch to change the default, let's see what
