[OpenAFS] AFS cell path shortcuts

Hello, we are shortly going to have an opportunity to do some redesign of 
our AFS cell, and I'm wondering what others have done in the following 

Currently, on all of our machines, we have a local filesystem link "/:" 
that points to either the RW cell (/afs/.glue.umd.edu), or the RO cell 

(/: was picked following the DCE/DFS convention).

This makes it very easy for us to switch a machine from looking at the RO 
cell (production) to the RW cell (development), without having to specify 
alternate paths.  Everything on the machine references /: instead of one 
of the direct paths.  i.e.,  /usr/local is a symlink to 
/:/system/1.5/@sys/usr/local.   So you can install things into /usr/local 
by switching one symlink.

This scheme works superbly with one exception- the ':' character won't 
work in certain places like PATH, LD_LIBRARY_PATH, etc.

I'm thinking of replacing the /: link with something like /cell to 
eliminate this problem.

Has anyone else done something similar?
