[ale] File system

[Christopher R. Curzio]

There is no possible way (that I am aware of) to switch unlike filesystems
on a partition without destroying data. However, if you just want
journaling capability in your FS, you can just create a journal file on
your ext2 partition to make it ext3. 

Make sure you're running 2.4.15 or later, and an up-to-date version of
fileutils. Be sure  ext3 support is compiled into your kernel. Once you
have that, all you'd need to do is to simply run:

	tune2fs -j /dev/hdaX

You can run this on a filesystem that is either mounted or unmounted. In
the words of Velvet Jones, It's as simple as that. (BONUS: If for some
reason your computer croaks, you can still read the filesystem as ext2
with a bootdisk that may not support ext3.)
