Hi Wayne,
It probably is, but as I pointed out in the original post, the call to cron.daily is commented out in /sbin/init.d/boot. WHY?? OK, now for us dummies, if it (cron.daily) is NOT called by /sbin/init.d/boot WHAT DOES call it? Yes I see that cron.daily is in the /etc/crontab script but how does that run. Who/What calls /etc/crontab. It isn't clear, to me, and no one has come forward to explain it. I have asked the same question more than once. It is not in the book! The man page included in SuSE 5.1 covers the crontab -e method only. Why has SuSe changed methods and not included the relavent man pages?
man cron says:
[...] Cron searches /var/cron/tabs for crontab files which are named after accounts in /etc/passwd; crontabs found are loaded into memory. Cron also searches for /etc/crontab which is in a different format (see crontab(5)). Cron then wakes up every minute, examining all stored crontabs, checking each command to see if it should be run in the current minute. When executing commands, any output is mailed to the owner of the crontab (or to the user named in the MAILTO environment variable in the crontab, if such exists). [...]
As you see /etc/crontab is not assigned to any user, it's kind of a 'system' table for regular jobs.
I think it's not a question of SysV or not, it's just an additional file to place jobs for regular sceduling. The line in /sbin/init.d/boot is usefull if your isn't up 24h.
crontab -e works still like it's supposed to be. You can have a crontab for root and any other user...
Bodo How stupid of me. Why did I only look for information on crontab in crontab Man pages. I should have looked in cron. ;-(( Ok, so I guess that any cron jobs should be put in /etc/crontab. Now may I ask, what are the advantages f any, over crontab -e? wayne
