If all of your systems are *identical*, try something like rsync
or rdist (both can be told to use ssh too).
1) build your kernel and install it on your development box
2) do a test boot. Ensure everything is there for you as needed
3) build a Distfile like so:
##################
HOSTS = (
host1
host2
host3
)
KERNEL = (
/boot
/etc/lilo.conf
/etc/grub.conf
)
kernel:
${KERNEL} -> ${HOSTS}
install ;
# could use a cmdspecial after this to run lilo if needed
modules:
/lib/modules -> ${HOSTS}
install ;
################
Now, run rdist -P/usr/bin/ssh -overify -f Distfile
You should see it verify what will be updated on hosts[1234...]
Once that's done run a shell loop to reboot the systems as required
for i in host1 host2 host3 host4 ; do
ssh $i "shutdown -r now"
done
If they are not identical, you can do the same thing, only different /boot
and /lib/module directories to each host would be required as well
as seperate Distfile rules for each host or group of hosts.
Hope that helps.
