>Environment:
The FreeBSD FAQ, on 4.x-STABLE
>Description:
The FAQ entry on dealing with root errors after mangling
crontab is slightly out of date. In particular, it suggests
just removing the crontab file, instead of the (slightly more
correct) -r option to crontab. Personally, I feel that people
should be using the periodic mechanism for
daily/weekly/monthly tasks instead of cron anyway.
>How-To-Repeat:
Read the FAQ and the crontab man page.
>Fix:
Here's a patch to the faq's book.sgml that replaces the suggestion to
delete the file with one to use "crontab -r". It also adds a paragraph
recommending periodic for daily/weekly/monthly tasks, along with a
pointer to the man pages.
