Starting off from jgarzik's fuse-ext2 priliminary code base, this is working implementation of ext2 file system in FUSE. The code is whipped so badly that I'm in no condition to send patches to jgarzik on this. This code is forked from the another file system kiddo prototype that I'm developing, which is based on ext2 and it uses this code. This is part of the reason why this fuse-ext2fs code looks entirely different from jgarzik's tree.

git tutorial here: http://www.kernel.org/pub/software/scm/git/docs/tutorial.html could be useful.

Requires libfuse and libext2fs.

FUSE is a neat way of prototyping a file system and this fuse-ext2fs would certainly be of help if you want to base your filesystem on ext2 and modify it thereafter.
