[rancid] jrancid excess revisions due to expect prompt mismatches?

[Chuck Liggett]

Gareth:

Switching the shell from /bin/bash to /bin/sh appears to be looking promising.  The spurious
commands in the body of the config have gone away the first run after the shell change.

Off the top of my head, it could be either the shell or pager not being called correctly. When you run it manually you
will be in a specific shell, but when run from cron, it will be using root's default. Can you try exporting the shell in the
crontab ?

Cheers,
Gareth

While querying a Juniper SRX 650 firewall cluster from a CentOS 6.4 box running Rancid 2.3.6 (rpm from Epel), Expect 5.44.1.15,
where Rancid is run out of /etc/cron.d/rancid and scheduled every quarter hour:

Several times a day, I get excess revisions where it looks as though a Juniper Rancid command appears in the body of the config as if more than one command is being sent in response to a prompt.

Every time I run it manually in expect debugging mode, it does not experience the issue.

Here's an illustration:

Sometimes, the commands are well within the body of other command output, like in this example:
