Repository on Mounted Network Drive

[Wayne Call]

What are the advantages of putting the Repository on a Mounted Network
Drive?  The purpose for putting the Repository on a network drive is so that
it automatically gets backed up by the Network Administrator.  The software
will get checked out onto a Linux Computer or Computers, and then the
software will get checked back in to a Mounted Network Drive.  The
Repository will be on a Mounted Network Drive.  What are the gottchas for
this type of development setup?  What would be another option?

I'm running into trouble with the cvs locks.  I can check out software, but
I cannot check in software and get the following error:

cvs commit: failed to create lock directory for '\mnt\ .....'

This error is produced because I'm a guest user and the cvs attempts to
create a lock on the Mounted Network Drive.  It was suggested to me to put
the locks in another directory rather than the Repository, but I believe I
would still have the same problem.

Any suggestions?
