Re: log file rotation in hamm...

["Alan Su" <alsu@beowulf.ucsd.edu>]

OK, both Norman and Shaleh didn't understand my question.  i can only
conclude that i'm an idiot.  =)  here's a second shot:

these are the output of 'syslogd-listfiles' and
'syslogd-listfiles --weekly':

  alsu# syslogd-listfiles
  /var/log/syslog
  alsu# syslogd-listfiles --weekly
  /var/log/messages
  /var/log/mail.warn
  /var/log/mail.err
  /var/log/mail.info
  /var/log/uucp.log
  /var/log/lpr.log
  /var/log/user.log
  /var/log/ppp.log
  /var/log/kern.log
  /var/log/auth.log
  /var/log/mail.log
  /var/log/daemon.log
  /var/log/debug

/etc/cron.daily calls 'syslogd-listfiles' and concludes that
/var/log/syslog should be rotated daily.  /etc/cron.weekly calls
'syslogd-listfiles --weekly' and rotates all the other logs on a
weekly basis.

the change i want to make is to rotate /var/log/syslog on a *weekly*
basis, rather than a daily basis.  as Shaleh points out, this
particular modification can be accomplished by simply moving
/etc/cron.daily/sysklogd to /etc/cron.weekly/sysklogd2 or something.
i claim this isn't the Debian Way, but rather a hack.  for example,
how would one make /var/log/messages rotate daily rather than weekly?
i would like a way for  'syslogd-listfiles' and
'syslogd-listfiles --weekly' to output something like the following:

  alsu# syslogd-listfiles
  /var/log/syslog
  /var/log/messages
  alsu# syslogd-listfiles --weekly
  /var/log/mail.warn
  /var/log/mail.err
  /var/log/mail.info
  /var/log/uucp.log
  /var/log/lpr.log
  /var/log/user.log
  /var/log/ppp.log
  /var/log/kern.log
  /var/log/auth.log
  /var/log/mail.log
  /var/log/daemon.log
  /var/log/debug

it seems to me that there should be a way to do this, but currently it
requires an act of god, or at least some really gross changes to
/etc/syslog.conf which will probably change the way stuff gets logged.
(i admit, i don't really understand what facilities and priorities
are, which is what syslogd-listfiles uses to decide when things need
to be logged.)

looked at it another way, my question could be, "why doesn't
syslogd-listfiles have it's own config file which describes directly
when things should be rotated, rather than inferring that from
/etc/syslog.conf?"

does this make sense?
