After my Raspberry PI died, I decided not to get a new one immediately. Instead, I turned the older laptop into a FreeBSD server. I use this server for Git, backup via ZFS snapshots, running Debian/RHEL VM using bhyve, side project web server and jails with ZFS. It works perfectly, but during monsoon season, the electric supply at home goes for hours, and my battery backup UPS only works for 15 minutes. Hence, when my FreeBSD laptop starts to run out of battery juicy, I want to shut it down automatically to avoid sudden filesystem and other corruption issues.
