Here is the procedure I've followed. It isn't listed anywhere as the
`official' method, and while it works for me, I take no responsibility if it
makes your server ignite or your users hate you. As always, run a backup
before you start the upgrade.
First off, here is an installation method from the jail(8) man page:
D=/here/is/the/jail
cd /usr/src
mkdir -p $D
make world DESTDIR=$D
cd etc
make distribution DESTDIR=$D -DNO_MAKEDEV_RUN
cd $D/dev
sh MAKEDEV jail
cd $D
ln -sf dev/null kernel
My upgrade process is pretty similar. Start with the generic system upgrade
method from /usr/src/UPDATING:
cd /usr/src
mergemaster -p # (to add any users required to build world)
make buildworld
make buildkernel KERNCONF=MYKERNELCONF
make installkernel KERNCONF=MYKERNELCONF
make installworld
mergemaster -C
Now, for each jail on your system:
D=/path/jailN
make installworld DESTDIR=$D
mergemaster -C -D $D
When finished:
reboot
This works on my system. Anything I've missed, anyone?
