Mythtv logging

Hello All

I'm not a huge fan of the current mythtv logging method which results in 
huge amounts of separate log files, so I've changed to using syslog.

This involves changing the command in init.d/mythbackend to "--syslog 
local7" instead of "--logpath /var/log/mythtv/"

This works great, but every time I upgrade the init.d file is 
overwritten. Is there anyway of stopping that file being overwritten by 
the upgrade each time?

cheers
