I prefer to use ReiserFS (it's a little faster than EXT3 for the stuff I
do) but I know for a fact that EXT3's reliability is proven.

	I had a laptop hard drive on me die recently, IBM TravelStar 15GB, it
had been making bad noises for quite some time, and I knew it was a
matter of time.

	One morning, it had been working fine, until an hour later, the machine
kept stalling -- waiting for data from the hard drive.  5 minutes later,
the machine was completely stalled, waiting for the hard drive.  The
hard drive was going absolutely bezzerk, trying to read the data.

	I tried rebooting -- no go, Linux refused to mount the root filesystem,
instant kernel panic.

	Later that night, I was home, I ended up grabbing a rescue CD I had
(actually RH8.0 disc 1) and I ran the e2fsck tool from there.  Once the
dust had settled, I was able to recover every byte of data on that hard
drive, dispite its hissy fit earlier that day.  In fact, I was able to
reboot off the hard drive, and boot linux normally after the filesystem
check.

	So you might want to consider EXT3/ReiserFS.  EXT3 should be an easy
upgrade, it's possible to initialise an EXT3 journal on an existing EXT2
filesystem using the e2fs tools.
