I haven't tried this, but it sure looks like one could build rancid with
./configure --prefix= ..etc..
and have /usr/local/bin/sendmail_alt be just
and that would take care of not sending emails or doing something
other than sending mail. Yes? but that means you'd have to build
rancid instead of just installing from some repository..
In any case, I went with changing control_rancid because there were a
few other things I wanted to do like filtering out passwords, keys,
hashes, etc. from the mail msg before sending it. So right after the
# Diff the directory and then checkin.
section I added
# -LR- begin: remove passwords, etc. from diff listing
/usr/local/bin/sanitize.sh $TMP.diff >$TMP.diff2
/bin/mv $TMP.diff2 $TMP.diff
# -LR- end : remove passwords etc. from diff listing
