Yes, it is good enough.

For me long-button press does not reboot, but leaves the phone in some
kind of permanent-off state.

For better interactive performance (ssh), turning off power_save
should help a lot.

I may try, thanks.

Would it be possible to package unicsy_demo?
https://github.com/pavelmachek/unicsy_demo Right now it is useful for
driver debugging, for example it can estimate battery remaining even
when battery is not calibrated. It can also reboot / poweroff the
machine, and read various sensors... When ofono is integrated, it can
also initiate calls and handle SMSes...
