filesystem

[Bill Cunningham]

    I hope this is the right list. I have created an ext2 filesystem and 
removed the dir_index feature. I don't know if this kind of experimentation 
is going to help me learn something about filesystems or not. Well what is 
dir_index? Then I ran e2fsck -f -v -pD and the /dev file. Now what did I 
remove? Htree. I guess it can always be put back and it's on an experimental 
filesystem.

    What features separate ext4 from ext3 ? I have noticed too that ext2 
fragments quite a bit.
