Everything is implementation dependent. There's no ISO cron standard or anything.

Both allow any user in the cron group to have their own crontabs by default, and both support optional .allow/.deny files

- bhaney 2y agoThat's a light spec for a subset of the interface and behavior of the crontab command line frontend, not a standard for cron in general. It's not really relevant to a discussion about how distros set up their cron defaults for per-user access. Thanks for sharing it though. I wasn't aware it was in the posix spec and it explains why pretty much every implementation supports .allow/.deny files even when most already implement better access control mechanisms.
