[CoLoCo] I'm confused about how the disk works

[Kenneth D. Weinert]

Hmmm, doing some searching I *might* have found a bit of an issue. You
can see the UUID in /etc/fstab, but when I run the command

sudo vol_id /dev/sda5 I get a completely different UUID. Should I just
replace the UUID in fstab with the one from the vol_id command?

Let me put it a different way - I'm *going* to give that a try, see if
swap will start up automagically.
