Hi
Thanks for a very nice piece of software.
I have a tiny suggestion for upslog.c.
It adds a signal handler for the USR1 signal, which simply triggers it
to abort the current sleep and log the requested now.
I find it useful because my upssched-cmd can then killall -USR1 upslog
to ensure that there is an entry in the log for brief power dropouts
which would otherwise be unrecorded (because the power is only off for a
few seconds).
I think that the patch is still valid against the latest source in GIT
but was originally coded against 2.2.x.
thanks
Andy
