Hi,
I wrote an extensive zsh completion script for initctl and it's aliases.
It's based on Mildred original script from 2007 but updated for natty and with
lot's of improvements. (had quite some fun, zsh is a great shell :-)
It's also been thoroughly tested by myself and friends.
So now I'm posting it here in the hope that it's helpful :-)
File is attached and/or available here: http://paste.grml.org/429/
Cheers,
Bernhard

Mmh - wouldn't it make sense to start a collaborative repository where
all the completion scripts could be comitted to?
Then everybody could pick the repo and take the files he/she likes.
Maybe it already exists?

Thanks, it looks like no one else has done this so I've committed it to
the archive and it'll be in 4.3.12.

Er, yeah, sorry. If you slip and press tab twice when you test it, it
still works :).

Now that I look at it again, could that typeset -g be outside the
_initctl() function without the if, so it's just run once (when the
whole file is autoloaded)?
