This setting means the service is attempted to be started at most 3
times within 5min. By default current systemd allows services to be
started at most 5 times within 10s. The default can be controlled with
DefaultStartLimitIntervalSec=/DefaultStartLimitBurst= in
/etc/systemd/system.conf.

Note that these settings apply to any kind of start, i.e. both
"systemctl start" and "systemctl restart".

I cannot parse this, sorry.

Note that "systemctl reset-failed" will also reset the restart counter
of a unit these days. Also, if a unit is not pinned into memory
because some other unit references it in some way it gets unloaded
right-away and along with it the restart counter. This means restart
limiting is ineffective if units are not referenced continously.
