Is this a typo, or is there really no newline? Also, make
sure /etc/rc.d/rc.test is executable, and the interpreter is correct

Well, the notify_file gets run when the leases are written out, so if
the leases are "never" written out, you'll never get notify run.

The readme says exactly what I want to say:

The udhcpd.leases behavior is designed for an embedded system. The
file is written either every auto_time seconds, or when a SIGUSR1
is received (the auto_time timer restarts if a SIGUSR1 is received).
If you send a SIGTERM to udhcpd directly after a SIGUSR1, udhcpd will
finish writing the leases file and wait for the aftermentioned script
to be executed and finish before quiting, so you do not need to sleep
between sending signals. When the file is written, a script can be
optionally called to commit the file to flash.
