nut

Set up Network UPS Tools (NUT) and configure it to send email notification on Arch Linux.

This role depends on roles/msmtp.

Tasks

• Install nut.
• Edit /etc/nut/ups.conf, /etc/nut/upsd.users, /etc/nut/upsmon.conf
• Create /etc/nut/msmtprc for sending email, use the variables from roles/msmtp. Because NUT runs as user nut who won't be able to read /root/.msmtprc file, create a same file at /etc/mut/msmtprc for nut user to read.
• Copy nut_notify.sh, which will be executed to send email notification.
• Enable various systemd services.
