Hi guys.
I have a dev server for our developers that holds around 40 jails,
each jail has php, mysql, python etc.
The server is now 7.0 and was wondering what is the best practice to
maintain security patches and kernel updates and I came out with the
following idea :
1.- freebsd-update fetch install ( host system)
2.- rebuild kernel ( I have a custom kernel )
3.- ezjail-update -b ( update basejail for all jails )
4.- run in cron portaudit on the jails for thirty party security
updates
5.- run portupgrade in case of a security update or for apps upgrade
on the jails.
sysutils/jailctl uses a pre-built /usr/obj to upgrade jails using
installworld etc. Newer versions (not yet in ports) support using
'template jails'. The latter is what we use.
Basically the update procedure goes like this: freebsd-update the
template jail, freebsd-update the host, reboot. I have found freebsd-
update to be an incredibly time-saver compared to buildworld/
installworld, and the IDS function included - despite not being a
really efficient IDS tripwire-style - is extremely useful for us in
determining which of our multiple-dozen jails need updates of binaries
or configuration.

I red in some forums that if you run freebsd-update you will need to
do a portuprade -fa to reinstall all the thirty party apps because
freebsd-update could upgrade or remove some libraries linked to
that programs, is this true ?, will be better to run a cvsup and
instead ?
That are some points of my idea but reading on internet I finished
more confuse about how will be the best way to do this.
any ideas will more appreciate.
Thanks.
