I just discovered and installed the _xguest_ package for Fedora 8 and 9. Here’s what it does:
> Installing this package sets up the xguest user to be used as a temporary account to switch to or as a kiosk user account. The account is disabled unless SELinux is in enforcing mode. The user is only allowed to log in via gdm [or the fast-user-swiching applet]. The home and temporary directories of the user will be polyinstantiated and mounted on tmpfs.
Here’s how to install it:
yum install xguest
I hit a brick wall when I first tried it. I thought my machine was in SELinux Enforcing mode, when it wasn’t — it was in Permissive mode. I fixed it using system-config-selinux.
It’s possible to change what the xguest user can do using system-config-selinux. I’ve attached a screenshot showing what capabilities can be granted or revoked.
