Hi,
Find below a patch to add support for DragonFly BSD to e2fsprogs. In the
case it gets rejected please indicate a reason so I can get it fixed.
For convenience I've uploaded the patch here:

Regards,
Antonio Huete

Subject: [PATCH] Add support for DragonFly BSD operating system.
- Add a new OS tag.
- DragonFly uses DIOCGPART to return disk information.
- Avoid falling to some old FreeBSD 4.x code blocks.
