The cron manpage says that /etc/crontab should have mode 0600. However, it is installed with 0644.
A /etc/cron.deny is installed without any users in it which means (according to crontab(1)) that all users are allowed to work with crontab. However, /usr/bin/crontab has mode 4710 which means that you must be member of the group cron to be able to use crontabs. Should I report a bug? -- gentoo-user@gentoo.org mailing list
