10 There's the UUID for the partition and the UUID for the filesystem living

22 It makes sense to me. TYPE refers to the filesystem type, look at the

30 I have seen things you lusers would not believe.
31 I've seen Sun monitors on fire off the side of the multimedia lab.
32 I've seen NTU lights glitter in the dark near the Mail Gate.
33 All these things will be lost in time, like the root partition last week.
