For an image, it's not really relevent what the format of the thing is. FreeBSD's VFS would need to change to be able to properly support a journalling filesystem. More specifically, the VOP_ABORTOP would need to become real, and the cookie portion of VOP_READDIR would have to go away, among other more minor tweaks. It's no coincidence that Margo's LFS code never worked quite right on FreeBSD, since a log structured FS is very similar to a JFS in its needs for transaction control. The only saving grace here is that while it would be very hard to wedge a writable NTFS into an unmodified FreeBSD VFS, it would be almost impossible to wedge it into an unmodified Linux VFS (their NTFS implementation is read-only, as well).
