i donno much the depths of selinux myself ;-) that's why i ahd problems with selinux enabled. anyway, my gut feeling is selinux is like NTFS security facility in Windows 2000/XP, which provides file level access control; who can access and what he/she can access; and what kind of access (Read, Write, Execute). but my cursory idea about selinux is that it gives you even more access control than NTFS. as in Windows, Administrator can do anything, no restrictions (i think so), but with selinux even root can be restricted in his authirties. that's what my shallow information is about selinux. with Fedora 2, i would be execising all facets of security which selinux provides. right now, i can't say much, some guru can answer authoritatively.
