[Gluster-devel] Init script

[Chris AtLee]

On my (debian) system, the 'initlog' command doesn't exist, so this
script prints out a lot of errors, and there are some issues with how
'kill' works.

init.d scripts are pretty hard to get working across multiple
distributions.  The best way I know of is to only rely on commands in
/lib/lsb/init-functions.

The attached script runs cleanly on my system.
