In the last year, I have run XFS, reiserfs v3, and ext3 on my laptop. I
mostly agree with you, although XFS doesn't really replace entire files
with zeros, just blocks that have been allocated but not written with
actual data...so /var/log/messages is likely to get some zeros in the
event of a bad crash. Files that were not being written at the time of
the crash are not affected.
Having run them all, my recommendation (and what I run currently) is
ext3. My soundbite summaries of each are:
XFS: aggressively caches, so might give you some power
savings...although real-world savings are likely to be slight to none.
Nice features (the only one that offers a free defragmentation utility,
even if it is brain-damaged). Cannot be shrunk, only grown.
Reiserfs V3: Excellent performance for _some_operations, slower
performance for others. Also can only be grown.
Ext3: Best journalling options available, including full-data
journalling if you want it and do not mind the slowness. Otherwise good
performance for the opposite operations as reiserfs. Can be grown or
shrunk.
I do not know of any Linux filesystem that can be resized while still
mounted.
