[rancid] missed cmds, but only when run from cron

[Alan McKinnon]

If it truly is a case that the script always fails when run from the
commandline and always fails when run from cron, then the problem is
almost certainly one of two thing

1. Your cron is set to run when something else is happening on the
network, and this increased activity is too much. This is rare.
2. Shell environment issues. This is very common as cron tends to run
with an empty environment and rancid's login shell does not.

Print out your environment as the rancid user and add likely things as
envvars to the crontab one by one till you find one that fixes the problem.
