[OpenAFS-port-darwin] anyone want to work on the installer?

[Derrick J Brashear]

so, the installer should set your (client) cellname instead of assuming 
you'll do it afterward. i have a simple cocoa app which does so and could 
be run from a postflight script. however, it's too simple. it should 
validate that a cell exists before letting you set it. anyone want to 
flesh it out and add a postflight script?

if you're really bored, you could let afsd options be selected (i can give 
you a meaningful list if you need one) and let the user add extra cells to 
cellservdb at client install time.
