[mythtv-users] delaying mythbackend startup until a STB is available

Over the weekend I had a power outage. My MythTV BE/FE is on a 900VA UPS and 2
ongoing recordings chugged merrily along until the UPS battery ran out - this
was a serious outage. I don't use the soft-shutdown capabilities of my UPS
monitor because outages aren't usually this long and it's a new UPS so I don't
know how long it's good for. But Linux seems to be remarkably robust so I've
never been zinged with problems after a power drop-out.
Upon power restoration the machine and my STBs restarted and one the
previously-recording shows picked up on my SD STB. The other recording had
ended during the outage.
But, mythbackend didn't see the HD STB because it takes a minute or so to
reboot, way slower than the machine takes to start up. I had to manually
restart mythbackend after the HD STB booted up.
So, I was wondering if there's a way to know, at boot time, if the boot is
happening after a power loss (not a normal shutdown), so that I could then
delay the start of mythbackend for a couple minutes after the machine reboots
to let the HD STB get itself together.
Any ideas?
