Yum in cron confusion?

[William John Murray]

  Hello FC3 users,
        I am confused by yum in cron, it doesn't seem to work for me.

  If I "/sbin/chkconfig --list yum" I see:
yum             0:off   1:off   2:on    3:on    4:on    5:on    6:off
which looks good.  There is a file '/etc/cron.daily/yum.cron' (which if
I run it interactively seems to update yum.)

/var/log/cron was run at 4am, but there is no sign of it having done
anything at all. Certainly my system was not updated, but where should
it leave any error messages? I can add debug by hand of course, but it
is a very slow turnaround, and surely there must be a log file
somewhere?
 I found a top about timing on: http://aaltonen.us/archive/2004/10/
which requires a file /etc/cron.daily/yum which I do not have. Is
my installation defective?

   Thanks,
           Bill
