Custom script in /usr/local/etc/rc.d, execution order/trigger question.

[w0w]

It looks like script placed in /usr/local/etc/rc.d executes twice, on startup and on shutdown. Am I right?
At least when I reboot using console menu, pfSense gives some message in console about stopping custom scripts and script produces some output, I just tested it with test output file. When I just quit the pfSense menu going to shell and typing reboot, script then runs only once on next boot. Is it expected behavior?

Are you sure that it's applicable to pfSense?

The behaviour of /usr/local/etc/rc.d scripts in pfSense matches what is described in that manual page so I have to assume that part is unchanged in pfSense.
