I'd agree with John that this isn't normal UNIX/Linux behavior, that
something somewhere has been added to the system code to cancel the
change you make to crontab.

As a kludge, you could add your "crontab /tmp/temp" to the end of
/etc/rc.local so that it is invoked again after the reboot.

Do a "crontab -l" periodically throughout the day to see if there's a
particular time when your reboot command disappears from it.
