TMP Directory on CVS Server - help!

[DW]

Hello,

I have a problem. I just built a new server to host our CVS server, and 
migrated to it last week.

Made a small oversight, though: took FreeBSD defaults when partitioning 
-- not good.

256MB /tmp directory is not large enough, and caused big problems last 
night when one of our developers was trying to commit.

I am going to build a new box with larger /tmp diretory, but in the 
meantime, how can I tell the server to use "/usr/local/tmp" as the 
temporary directory?

I see the $TMPDIR var, but am not clear on how to set it on the server, 
so this is what the server will use during commits, checkouts, etc.

Thanks for any help,

DW
