I am trying to run tests on another box which does not have its own monitor,
so was using ssh and ftp. I would like to run more than one computer using
power from a UPS, so I have been reading the documentation for Network UPS
Tools (nut). I was getting worried that nut had caused a problem, but I re-
installed without nut to confirm. One of the things I need to check is that I
can do a simple reboot on the master without everything else shutting down as
well. The latest update did require a reboot, and then I discovered the
problem. My local mains supply is not reliable, and there have been several
cable faults affecting the local area, but I am still much more likely to have
to reboot the master machine than deal with the results of a power cut.
