This reflects a systemd service sample file change made in borgmatic
1.7.6, commit 2e9f70d49647d47fb4ca05f428c592b0e4319544:
When backing up a machine with a monitor using logind to control
idle timeout and things like DPMS, borgmatic can block the screen
from turning on/off with systemd-inhibit. This is because by
default systemd-inhibit will block
"idle:sleep:shutdown". Borgmatic does not need to care about idle,
only about suspend and shutdown. So, add an explicit `--what` flag
for what borgmatic should inhibit.
For more information see systemd-inhibit(1).
