Why would a journal/log based filesystem be more reliable ?
From people working with True64 or irix, it's worse because Digital or SGI
doesn't provide a tool to repair the fs is something got really from.
At last with LFS we have a fsck. But I would still trust better ffs, even
when the known LFS bugs will be corrected.
Now I'm running LFS for a few filesystems, because its performances for
lots of small files is far better than FFS+softdep. It's good for
web caches and such (I also have my sources tree on it :)
Sure ext2fs is not a good choise but it's linux fault: as it's completely
async you can end up with a lot of things in lost+found after a crash; not
really easy to recover the original names. Also the 2G file size limit
is something annoying.
