Do you guys know of any floppy-based distribs that include perl?

I was loking for a solution that would be easier to make with a soldering
iron and keyboard than with a credit card, but that does sound reasonable.
I'm considering runing one of the UPS daemons and just sending a power-off
message to the serial port (it's usualy just a given pin that goes from high
to low, IIRC).  I'll have to switch to an ATX power supply then and do
something that'll both send a pulse to the power-on on the motherboard when
power's applied to the ignition.  It ends up that I'd need like a starter
switch kind of thing because I want the power inverter to come on when the
ignition is turned on, and I want the power inverter to remain powered until
the computer is completely shut down (or at least the disks are unmounted
cleanly).  Mounting everything read-only would prolly be easier...  If I had
room under the dash for a UPS, that'd be great though.  Did you have a
specific UPS that is real small and has a linux-able serial control port in
mind?
