The man page for batch (part of sys-process/at) lists the wrong path for its config-files. /usr/lib/cron/at.allow and /usr/lib/cron/at.deny should be: /etc/at/at.allow and /etc/at/at.deny. (See at-man-page, as batch is only an alias) Reproducible: Always Steps to Reproduce: 1. 2. 3.
Thank you for report. But, please, recheck. Seems that you are talking about /usr/share/man/man1p/batch.1p.gz which comes with sys-apps/man-pages package and not about batch man page which comes with sys-process/at. Right?
batch(1p) documents the POSIX requirements: http://www.opengroup.org/onlinepubs/009695399/utilities/batch.html nothing to change here
