So really -- you may not like it, but zeroing it is the safest thing
to do (besides being a security requirement).


In other words -- other files systems leave those files in a corrupt and
undefined state. Are you saying this is preferable?

Of course - if it allows me to recover my config file :-P

Haha, yeah, except that it could also allow someone else to recover your
mail cache instead.

Really, I was sometimes happy that old reiserfsck --rebuild-tree basically
dug up all the stuff that ever was written to a disk, after an accidental
rm ;-)

But to put some constructive things onto the discussion: I think that ext3
(or maybe nowadays ext4) is still a reasonable default file system for the
root and boot partitions. For data partitions, I also use XFS, and am
happy with its performance. Until I want to delete a large kernel source
tree. Then I'm always annoyed ;-)

Besides, you cannot install a boot record onto XFS, so you always need a
second partition anyway (Might not be 100% technically correct. You
cannot install grub into it at least).
