I'll answer both at once. You change the attribute bits with chattr and
list them with lsattr. The problem with Reiser is that when you
chattr +i filename you then do an lsattr filename and find the 'i' bit set.
But it's not honoured.
The documentation states that those utilities are part of the ext2utils.
I've read that they work on ext3 as well (which makes sense). I'm
-guessing- that they "pretend" to work at all at the VFS layer, but the
actual filesystem module doesn't kick back any fatal errors--just
gracefully ignores the fact that it's there.

Damn, I remember when DVD media was like $2.50+ a crack.
Then again, I also remember when CD-R blanks were $1/ea. :)
Hell, I remember a day and age when I used to pay $20 as a matter of course
for 10 DS/DD 5.25" floppy disks.
