>From what I understand, since I use Linux as well, is that EXT3 is
really a sort of journalling layer above EXT2, since you can mount EXT3
systems as EXT2 - just without the journalling. Since FreeBSD does have
some support for EXT2 already, would it not be a possibility ..shortest
road to Rome -- to extend EXT3 functionality into it ?
But then I guess the Stallman factor comes into the equation.
But I do agree it would be nice to have journalling available somehow.
Rebooting an incorrectly shutdown (crashed) Linux FS using EXT3 or
Reiser you miss the repairs going on if you blink.
There is of course the operational consideration of speed of disk i/o. I
have read conflicting reports on reiser as to whether it is
significantly slower or faster than EXT2 -- seems to be dependent on
number and size of files on the system.
