Hi,

Thnaks for the lites document. Porting the entire file system from NetBSD will be quite difficult and the current implementation has only parts under
GPL so my plan is to rewrite only those parts.

My plan is
- freeing ext2fs from GPL.
- making it MPSAFE (after SoC).
- adding new features like journalling (possibly using gjournal ), extended attribute support etc.


Cheers,
