Package: cronic
Version: 3-1
Severity: wishlist
Tags: patch upstream
Dear Maintainer,
An increasing number of applications we use through cron are putting
debug output on STDERR while returning 0 by default, and cannot be
quietened. Examples include docker and gitlab maintenance
We have locally patched our cronic to support an option, -r, which will
cause cronic to only generate a report if the return code is nonzero,
even if there is STDERR output. We submit it for your consideration.
