That sounds like a good plan.

For the kernel module, there has been a version in FreeBSD since the
late 90s.  The tricky parts are about vfs protocol changes and widths of
types.  I would recommend reading the history of both the FreeBSD and
NetBSD kernel modules.  There were a few recent fixes to the NetBSD
version, but I think those may not be applicable to a FreeBSD-derived

Also, there were two kernel protocol versions, and only one is of
interest now.   It's sort of on my todo list to purge the old one from
NetBSD.  I think there was version 4, for coda-4.x, and version 5, for
5.x and 6.x.

Coda's kernel module is somewhat like FUSE.   I have long thought that
coda should have a fuse backend, rather than a custom kernel module.
That's probably more work than porting the kernel module to DragonFly,
but also of much broader utility.
