How to rename an existing/working partition?

[Jim Christiansen]

I have sort of a regular method upgrading my Redhat/FC servers by using two 
drives and multiple partitions.  My usual  habit for upgrading systems is to 
recable my old and working master to slave and the old slave to master and 
at install not to reformate the old master-  I just relabel it as 
/old-slash.

After everything settles down I clear off the /old-slash in stages and then 
write an rsync script to take my new homes across at midnight everyday...

I'm getting tired of seeing /old-slash show up in the root of my file 
system.

I'm using FC5 now and want to rename /old-slash to something less boring :-) 
  - maybe /backup or maybe /rsync-drive...

Does anyone know how to do this??  I've searched around but not found 
anything clear yet.

Thanks,  Jim
