One of the annoying things about User ID's is that most Distros user utilities start at some number and count up. Then when you use nfs or removable media you find that the files are now owned by another user.

It would be nice if the default was to pick a random arbitrary and large UID so the chance of UID clashes would be remote.

Simple, I was trying to be funny. Notice the smiley :)

When is the patent office going to quit giving patents for obvious techniques? :)
