OK, time to put your tin=foil hats on for a moment, bare with me. Any
journaling filesystem is bad if you're interested in making deleted
files as hard to recover as possible. Yes, I understand ext3 is a good
fs and is pretty much the standard nowadays,  but would we really be on
a SELinux mailing list if we weren't just a little bit crazy and
paranoid? I don't know enough about the other fs's you mentioned to know
if they are journaled, but perhaps its something to consider.
