`/vol'
======

   `/vol' is used as a catch-all for volumes which do not have other
conventional names.

   Below is part of the `/vol' map for the domain `doc.ic.ac.uk'.  The
`r+d' tree is used for new or experimental software that needs to be
available everywhere without installing it on all the fileservers.
Users wishing to try out the new software then simply include
`/vol/r+d/{bin,ucb}' in their path.

   The main tree resides on one host `gould.doc.ic.ac.uk', which has
different `bin', `etc', `lib' and `ucb' sub-directories for each
machine architecture.  For example, `/vol/r+d/bin' for a Sun-4 would be
stored in the sub-directory `bin/sun4' of the filesystem `/usr/r+d'.
When it was accessed a symbolic link pointing to
`/a/gould/usr/r+d/bin/sun4' would be returned.
