[Libguestfs] [PATCH nbdkit 00/10] FreeBSD support.

With these patches, a majority of tests pass.  The notable
things which are still broken:

 - Because FreeBSD links /home -> /usr/home, $(pwd) gives a different
   result from realpath(2).  Therefore some tests which implicitly
   rely on (eg) a plugin which calls nbdkit_realpath internally and
   then checking that path against $(pwd) fail.

 - Shebangs (#!) don't seem to work the same way under FreeBSD as
   they do under the Linux kernel.  In any case ‘#!/usr/sbin/nbdkit perl’
   runs the script under the shell.  I didn't investigate why so far.

 - You have to use GNU make (gmake).  BSD make gets very confused by
   automake Makefiles.  I don't know if it's something we're doing
   wrong or if it's just not supposed to work.

Rich.

[Libguestfs] [PATCH nbdkit 01/10] common: Allow common/ functions to be used by core server.

Originally the common/ directory was only for common code shared by
plugins and filters but that we didn't want to include in the core
server.  However we might as well make the code under common/
available everywhere.  (This now works the same way as the libguestfs
common/ directory.)

[Libguestfs] [PATCH nbdkit 03/10] freebsd: Make endian functions work on FreeBSD.

Introduce a new "byte-swapping.h" header which encapsulates the
differences between platforms.

the replacement is probably not thread-safe, but there's not much we
can do about that.

PATH_MAX need not be defined (think GNU Hurd, for example), or may be 
insanely large where you are wasting time overallocating then shrinking 
in the common case. A more robust implementation starts with a smaller 
size, then repeatedly grows the buffer as long as getcwd() fails with 
ERANGE. Or, you could use realpath(".", NULL), to get an equivalent
(but
not necessarily identical) name, with the malloc() taken care of on your 
behalf.

But I don't think we need to worry about that for BSD, and that your 
implementation works fine for now.

This loses the '-' argument that used to be passed by the kernel (but 
you can't add it back to the #! linew without using BSD's or GNU 
coreutils' recent addition of 'env -S').  Is it worth adding a
'set -'
line later in the script to compensate, if you were previously passing 
the '-' as a way to reset the shell from inheriting environmental 
differences?

Theoretically, automake should produce makefiles compatible with BSD 
make as long as you didn't introduce any GNU make'isms in your 
Makefile.am files. I don't know if the problem was an actual GNU 
make'ism, or a bug in BSD make, but I'm also not too worried about this 
(after all, both libvirt and qemu require GNU make as a conscious 
choice, so people on BSD systems are already used to using gmake rather 
than figuring out whether BSD make can do the job).
