What is the easiest way to change the numerical value of a user's user id under Fedora Core 2? I don't see the option to do that under the graphical Users and Groups System Settings utility? Or do I just have to manually edit /etc/passwd and /etc/passwd~ to change the user id and then chown -R on the user's home directory? Jack ps I need to do this to be able to exchange data off of some SGI optical disks that all have a different user id for the same user name.
