After upgrade from sys-process/fcron-3.0.6-r2 to version 3.0.6-r3, the permissions set on fcrontab executable prevent non-root member of fcron group from successfully executing commands fcrontab -e or fcrontab -l. Compared to the previous revision, the executable has setuid flag unset and setting it, e.g. with chmod u+s $(which fcrontab), makes fcrontab usable again. The changelog for fcron-3.0.6-r3 says that modifications of some files' permissions were removed during postinst phase, so I'm not sure if I configured fcron properly, but maybe permission changes are necessary at some point. Reproducible: Always Steps to Reproduce: 1. emerge -av =sys-process/fcron-3.0.6-r3 2. Add selected non-root user to group fcron. 3. Execute fcrontab -e or fcrontab -l as selected user. Actual Results: Instead of editing or listing the user's crontab, following message is displayed: could not change euid to <fcron-uid>: Operation not permitted Expected Results: User's crontab should be opened for editing or printed.

Ah this is mine — I actually was fixing that today when I installed fcron on a different system, looks like the one I was testing on has a quiiite different setup (probably old relics). Will commit the fix tomorrow.
Fixed in -r4.
