audit log written whenever cron wakes up, keeps disks spun up

I was checking a new F10 system for disk writes on an otherwise idle system, and it seems that each time cron wakes up, it generates audit messages, which causes a write to /var/log/audit/audit.log, which keeps my disks spun up even when I'm not doing anything. :)
I don't know if the audit is necessary... if not, it might be nice to avoid this.
For most users these are totally useless, I couldn't care less on my machines.
maybe it could be done with some sort of user,never rule
but only being limited to uid, auid, gid, and pid in those rule types seems overly restrictive and couldn't be used to supress these....
Sure seems reasonable to me to come up with some way to turn these off...
I think you can set some buffering options for the audit daemon which won't write to the disk all the time. Try setting flush = none in auditd.conf.
I'm not sure that'll help; if auditd is writing to the log, pdflush will come along & flush it out soon even if auditd isn't syncing (I guess w/something like laptop mode, this could help, though).
But crond doesn't write to audit on each wakeup just on each job execution. So if you have jobs scheduled only once an hour it will write to the audit only hourly. The question is whether the system jobs (scheduled by root in /etc/crontab and /etc/cron.d/... files) really have to be audited or not.
This message is a reminder that Fedora 10 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 10. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '10'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 10's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 10 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
Fedora 10 changed to end-of-life (EOL) status on 2009-12-17. Fedora 10 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.
