The obvious other things, like mounting /boot, /usr, and so on, as read-only, puts one or two exploit vectors out the window, without ever having to mess with SELinux, as well. ;-) If you're of a similar vintage. > /tmp isn't nodev by default either, but you can change that if you were > hardening it all up I suppose.

Using multiple partitions, rather than just one or two; with LVM being a separate issue (those partitions could be part of LVM or something else), and LVM being pointless on a system that could only have one drive, anyway (such as most laptops, and a lot of the small desktop cases). Another issue against LVM is trying to repair a system if it goes wonky. If your first LVM drive goes wonky, everything else goes with it. And it doesn't seem ameniable to fsck. I was getting errors that seemed rather fatal, fsck couldn't help with the LVM disk. But I wiped and re-set up without LVM, and that disk drive passed all the error checks I could throw at it. Then there's the fun and games of trying to put one LVM disk into another box to read stuff from the drive. Dealing with two like-named volume groups seems even worse that coping with like-named volume labels. -- (This box runs FC5, my others run FC4 & FC6, in case that's important to the thread.)
