You might consider using some kind of "release lock" like wo do. We are
using NFS mounts for /home, and I have created a little init script
which will run on shutdown (Runlevel 0) and check if
/home/fai-update-timestamp is newer than the folder which
/var/log/fai/localhost/last-softupdate points to, and run a softupdate
only if it is.
This way, I can test updates and "release" them to the clients by "touch
/home/fai-update-timestamp" on the server.

I can post the init script if you like.

Bye,
Andreas
