In contrast to vfat, ext3 has full support for file privileges. It is
a very important security feature that a non-root user cannot just
change the ownership of a file that does not belong to him. Which
particular problem do you try to solve?

Please be aware that this does not change the mount point directory on
the 'parent' file system, but the permissions of the root file system
on the mounted device. This might be fine for your purposes, but is
not what some people expect.

That is not applicable. Because ext3 has proper file system
permissions, ext3 does not have an umask option. This only makes sense
for file systems which do not know about permissions, like vfat.

I don't understand this - if you change the owner of a directory from
root to 'joe', then of course joe can write into it -- that was the
whole point of the ownership change.
Can you please clarify this?
