This crontab I installed using sudo crontab -u public -e cause I was
desperate for the crontab to be running asap

tim at camiroi:~$ ls -l /var/spool/cron/

drwx-wx--T  2 root   crontab 4096 2005-08-18 22:44 crontabs

As for groups. I'm in all the same ones on camiroi (problem box) as
linjeni (my box). I'm in extra ones on camiroi for the domain. So src
backup ntpower ntadmins.

p.s. for reference i ran the same commands on linjeni. The only
difference I can see is which group the created crontab is in. crontab
on this box, root on the other. But that doesn't explain why I can't
create a crontab at all.
