Fuse works ok:
I created a zvol, exported on iSCSI, mapped from a W7 machine, partitioned,
formatted, copied some files onto it, unexported, then dd -d the partition
into a file, then mounted that, then copied the files from there, copied
another files to there, umount, dd-d back the partition with the proper
offset, exported again, and the W7 machine saw the new files, etc.
So, I didn't take a very deep check, but mount, and some basic read and
write operations surely work with ntfs-3g.

BTW.: Do someone know a best practice to access a partition in an image?
I googled a lot about that, and there were a plan to add an extra option to
lofiadm, and there you could gave a specific offset, but at least the
OI/Solaris line of lofiadm don't support that yet. As far as I could
conclude that, that feature was never implemented.

I tried to build a newer fuse-ext2, and downloaded 0.0.7 from
http://alperakcan.net/?open=projects&project=fuse-ext2
But It didn't worked. e2fsprogs had some errors on the beggining, but I
left it out, and just tried to build the fuse-ext2 part... I added some
include into fuse-ext2.h (fuse.h -> fuse/fuse.h, fcntl.h, sys/types.h,
sys/stat.h, strings.h, unistd.h), and most of the compiler errors gone,
but op_readdir.c still tried to use some macros/constants (DT_REG, DT_DIR,
etc.) which I can't provide.

Better ideas?

György
