This is a just wondering what would be best, or is it really needed to do this question.
I just did that install Void to a USB Stick thing. got x and fluxbox up and running.
when I installed grub, then update grub it puts the UUID into that file so it knows where to look to boot (yes?).
so I have no fstab entry for my root or anything other then this
[userx@USB16VoidLinux ~]$ cat /etc/fstab
# See fstab(5).
# <file system> <dir> <type> <options> <dump> <pass>
tmpfs /tmp tmpfs defaults,nosuid,nodev 0 0
it boots of course, because I am in it right now writing this. So is it an absoloute that one should really to be on the safe side add the root UUID into fstab also?
