How about having an NFS server with the patches and your servers
mount in to (say) /usr/local/patches/. Then setup a script in the
crontab to check for the file "start_patching" in that directory. If
it exists you run the "install_cluster" script, if not the script
exits.
You may want to stagger the times so you don't hammer the NFS server
too hard. Either by having the time different in the crontab, or
having a randomized sleep statement in the script. (Or both.)
Of course, having things happen automatically happen on 150 servers
allows you to mess things up very quickly on 150 servers.
