I agree with all of that. However, I've used ext3 from about kernels 2.4.4 as
I tried reiser on 2.4.2 and got bitten because it was buggey and lost the whole
of /var which then forced me to do a complete reinstall from CDs and then a
250MB download over dialup to get back to a current state (thank god for
apt-get). Ext3 seems stable - I've only once had an oops on me, but that was
because I'd compiled the kernel with the wrong version of gcc (I think I used
a 3.x version which still has issues with kernel AFAIK).
One interesting point is that the fast file system which uses soft updates and
is used on almost all *BSDs is seldom used linux: to me this seems odd
a paper at http://www.usenix.org/publications/library/proceedings/usenix2000/general/full_papers/seltzer/seltzer.pdf explains the advantages and
from what I can gather it seems as if it's faster and just as safe as journalled
file systems. Any comments?
