[ale] backing up /var -POSTGRES & LABEL

[Paul Cartwright]

ok,
I was successful in adding a new drive & moving /var to it! /var went from 96% 
full, to %3 full.
I had 2 issues that I still would like some info on ( for future use & 
reference:)

1. Even in single user mode ( init 1) /var would not unmount, said it was busy 
( postgres active??) I didn't know what to do. so I could not rename it, to 
move it to the new drive. Question, how would I know why /var was busy, and 
how would I stop postgres?

2. in /etc/fstab /var was a LABEL... LABEL=/var    /var......

I commented it out and added the new drive as :
/dev/sdb1 /var...

I'm not familiar with LABELS in fstab, could I have done it differently using 
the LABEL?

thanks for all your help!!
