[9fans] group ownership for shared devices

[Lyndon Nerenberg]

I have a CPU server running as 'glenda' that has a DVD drive. I want to 
make that DVD drive available to various terminals on the network. But I 
don't want to put the terminal users into glenda's group. The obvious
solution seemed to be to set up a 'commondevs' group, add glenda and the 
allowed device users to it, then have the CPU server 'chgrp commondevs 
/dev/...' but no joy there. There's got to be something stunningly simple 
here that I'm missing ...
