I ended up in adding:

Not perfect, really, but working at my side.

Yes, I can ;-) But! I do have a lot of service jails running at my host, thus I would like to omit modifying every jail's /etc/periodic.conf adding: | daily_status_pkg_changes_enable="YES"# Show package changes | pkg_info="pkg info" # Use this program > Try this patch: Thanks for that approach, namely adding "pkg -j jailname info" for every jail running. Due to my amount of jails I might need to add some looping over "jls -N" output instead of adding a lot of $daily_status_pkg_changes_flags. I was hoping that I could omit programming that functionality myself, but I might need to do so.

HOWTO monitor changes in installed packages within jails?
Hi -- I did migrate to pkgng some month ago, and ever since I am curious how to monitor changes in installed packages within jails. I am looking for a functionality/port that works like 490.status-pkg-changes for my host. Question: is there any functionality within the periodic system or a port that I might have missed to find? Thanks in advance and with kind regards, Michael ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"

I can confirm that Postfix, Dovecot, and Squirrelmail do run in jails, and I do assume that almost every mailing system will do as well.

gmirror+gjournal: spontaneous reboots on "excessive" disk access
Hi -- I'm running a gmirror raid1 plus gjournal for a year now. This is a 7.2-RELEASE-p6 right now. Both disks are regular ATA and healthy according smartctl. Sometimes, not always though, I do experience spontaneous reboots without leaving any hints in logfiles whenver I "beat" my disks "excessively". This might be something like: dd if=/dev/null of=/some/file bs=1M count=4k plus parallel disk accesses by mail and news server. If I omit all parallel disk access those dd's will run to completion without reboots, always. It might well be that there is something wrong with my hardware (co-located, no access to the console available). Thus, before addressing support I'd like to know: has anyone else seen reboots under those conditions?
