multiple nistances at boot with mysqld_multi or other

[Chris McKeever]

I am trying to get a few instances of mysql running at boot time - and
I have come across the command mysqld_multi.  Seems to have a lot of
documentation about kicking those off via command line - but not much
on setting it up to start at boot.  anyone have any insight into this?
 Either using mysqld_multi or a different startup script?

Thanks
