[svlug] What is with labels?

I'm trying to upgrade my system and rh9 is spazzing out because I've 
got directory subtrees that are symbolic links to trees on other
partitions. 

For example /usr is a partition and /vault is a partiion but
/usr/local is a symbolic link to /vault/local (I ran out of space on
the /usr partition).  I wanted to move /usr from /dev/hda6 to
/dev/hda11 (which used to be /vault).  

I made the changes in /etc/fstab:
LABEL=/usr           /oldusr                 ext3    defaults        1  2
LABEL=/vault              /usr                    ext3    defaults   1 2

And that sort of seems to work. It perturbs my sense of aesthetic that
/oldusr is on /usr and /usr is on /vault.

I can't seem to find any good documentation on how labels work, where
the data is kept (in a file, in the partition table, in the aether?)
and how it is modified.

Meanwhile the system complains about there not being enough space on
/var but a df shows it to only be 15% full.

/dev/hda6              3162420   2473856    527916  83% /oldusr
/dev/hda5              3162420    430664   2571108  15% /var
/dev/hda10             7906164   3540208   3964336  48% /var/www
/dev/hda11            23719032   6107248  16406912  28% /usr
/dev/hda12            21607920  15399224   5111060  76% /vault2
  

Can someone please point me to some decent documentation about how
labels, /etc/fstab and any other files or programs work?

Thanks
  Larry
