UFS on FreeBSD is not endian-agnostic. It uses the host byte order
for multibyte values.
As result, you can share UFS volumes only between hosts with the same
endianess, like i386/amd64/ia64 little endian or sparc64/mips big
endian.
AFAIK, NetBSD has such support.
Wow... I didn't realise that.
I thought UFS (1 or 2) takes all care
of endian-ness. Do you mean that even
I had say a SCSI internal disk with UFS2,
I couldn't move it between a little and
a big endian freebsd boxes?
So what is the advice for transferring data
via USB in such cases? Any other gpart partition
I could use?
In the end I burned a CD with the files in question,
but it's a bit of a waste, as I only need to
move over several KB of data (wireless setup).
Thanks
Anton
