That's the common case, that's handled well by any tool I looked at:
* laptops with exactly one AC and exactly one battery
* desktops/servers/boards with no power sensors of any kind

Systemd knows about multiple AC/multiple batteries, current powermgmt-base
also about old style not yet converted drivers (Powerbooks, ancient i386);
what I'm interested in are more exotic new style cases.

Your local MTA is not capable of delivering outgoing mail (that's the
default unless configured); unless you have some other purpose, don't bother
fixing this for my sake (your machines are already handled well).

Thanks for looking!
