I just read this, because I'm interested as well. It raises a question. 
Doesn't the Linux boot-sequence have a very specific ordering, with the 
number values of each service determining their sequence in the stack, and 
rc.local being last? If so, when does the script get executed using the 
crontab @reboot method? There didn't seem to be anything in the man page 
about that - am I missing something?
