Re: What is the best way to mount remote repositories?

[Laine Stump]

>From the description of what you're proposing, It sounds like each
site has its "main" projects (which aren't worked on much by other
sites) and needs occasional access to projects mainly worked on by the
other sites.

Some recommendations:

1) NEVER NEVER NEVER NFS-mount a CVS repository!!!

2) Setup a CVS repository locally at each site that contains only the
   "main" projects for that site, make those repositories accessible
   via ssh, rsh, or pserver mode, and just use different CVSROOT
   settings to checkout the SITE_A and SITE_B projects. Once you've
   done the initial checkouts to your work directories, you won't need
   to specify the alternate CVSROOT for update, diff, commit, etc
   commands - CVS figures it out by itself.

P.S. Make sure you give each CVS repository its own local CVSROOT -
don't try to NFS-mount it either (as you've suggested in your original
message)
