Journaling file systems revisited

[Jerry Feldman]

I think that ext3 is probably a bit more stable since it is essentially a 
lump on the existing ext2 file system. Reiser did have some early problems, 
but the current release seems to be ok. Both times I found corruption on my 
laptop I was able to fix it, but I also discovered that my 32MB memory 
module was bad, so I can't blame Reiser. However I tend to like the 
technology they are using. I won't paint myself into the corner though.
