Could you show me more context around this line from the file in the
configs/ directory?

How kinky are you willing to be to collect debug info?  If NOPIPE=YES is
set in rancid.conf and -d is added to the script line in rancid.types.base,
then .raw files will be left behind and the rancid-run cron can be altered
to collect those files, like so:

<timespec> <rancid-run cmd>; ; D=`date +\%Y-\%m-\%d:\%H`; mkdir -p tmp/$D && cp -p <rancidgroupname>/configs/*.raw tmp/$D

and when you next discover the change, we look at the input in detail.
