[rancid] Re: router config diffs - emailing stale info

Well I see the following in the FAQ - Q. I keep receiving the same diff
for a (or set of) devices, but I know the data is not changing
repeatedly. Why? A. This is probably a CVS or filesystem permissions
problem. Check the log file from the last run for that group for clues
first; it may provide the exact cause. Note: It is very important the
following be done as the user who normally runs the rancid collection
from cron. Check the cvs status of the device's file. example: guelah
[2704] cvs status rtr.shrubbery.net

1) I checked to ensure all the rancid and CVS files are owned by rancid
(chown -R rancid:rancid *)

2) I set the CVSROOT variable (/var/CVS) and then went into
/var/CVS/site-a/configs and type cvs status,v and it says
cannot open CVS/Entries for reading: no such file     cvs status: use
cvs add to create an entry     File:,v Status: unknown and no
entry or revision control file.

3) In the rancid log files I see some messages as follows: 
cvs commit: Up-to-date check failed for `configs/'
cvs commit: Up-to-date check failed for `configs/'
cvs [commit aborted]: correct above errors first!

4) Looks like a CVS issue but unclear how to resolve.

see the cvs section of the faq.
