[rancid] How to make SVN ignore select changed configs?

[Matt Almgren]

Hi, we have a few f5's that are controlled with scripts that will bring a node in and out of the pool.   The problem here is that every time rancid runs, it picks up on this "monitor up/down" change and fires off a Rancid SVN change email.

Based on this thread, I see there's a way to exclude some matching lines with CVS, but I don't see a way to do that with SVN – or at least not easily with the existing control-rancid script.

Here's the code in question in the control_rancid file:

if [ $RCSSYS = "cvs" ] ; then
    cvs -f diff -U 4 -ko | sed -e '/^RCS file: /d' -e '/^--- /d' \
        -e '/^+++ /d' -e 's/^\([-+ ]\)/\1 /' >$TMP.diff
else
    svn diff | sed -e '/^+++ /d' -e 's/^\([-+ ]\)/\1 /' >$TMP.diff
fi


Has anyone any tips for modifying that svn diff line to exclude "^monitor state" from the compared files?

Thanks, Matt
