[mythtv-users] Auto shutdown/startup advice needed

I have a working MythTV system. I'm trying to configure auto shutdown
and startup, and I'm running into some issues. I was wondering if
anyone had a similar system and could offer some advice.
I have a network with two backends and four frontends. It's configured
as follows:
* The primary backend does not have any capture cards. It hosts the
database and MythWeb. It will not be getting shut down.
* The slave backend has four capture cards, two analog cable and
two HDTV. It also is the main file server for recorded video.
* I run a frontend on the same system as the slave backend, but
exiting to MythWelcome is fine.
* The other frontends are on diskless clients that NFS-mount root
off the slave backend. I have wake-on-lan configured for these.
The main difficulty at the moment is this. I have the master backed
set up to wake the slave 5 minutes before a recording, and that
configuration seems to be working. However, as soon as I shut down the
slave all of the capture cards disappear, resulting in the recording
schedule being reset to empty. Hence, the slave backend is never woken
up - because the master doesn't think there is anything to record.
My immediate approach would be to create low-priority "fake" capture
cards on the master. This would result in the scheduling sticking
around, but a) I'm not sure the slave would ever be woken up and b) I
don't want to mess up the conflict resolution algorithm.
Increasing the complexity is our use of MythWeb as a primary
scheduling vehicle, so it is entirely possible that a new recording
will be scheduled while the slave is turned off.
This is with MythTV 0.21. Does anyone have any suggestions?
