Xen devel - Dec 2009 - Questions about Xen qemu-dm so I can finish my Debian packaging

Hi,

By default in xen-config-host.h, there is:

#define DEFAULT_NETWORK_SCRIPT "/etc/xen/qemu-ifup"

why isn''t it:

#define DEFAULT_NETWORK_SCRIPT "/etc/xen/scripts/qemu-ifup"

and can it be changed in the Git to be like this by default? Or should I
patch it in my package?

Also, I asked the following, and still got no answer about it:

1- What is qemu-nbd-xen for, and do I need to package it (together with
its manpage)? Should it go in /usr/bin?

2- Is there anything else than qemu-dm, or qemu-img-xen, that needs to
be present in this package?

3- By default, the xen-setup script does:

./configure --disable-gfx-check --disable-curses \
   --disable-slirp "$@" --prefix=/usr

but I saw in the help of ./configure that there is:
--audio-drv-list

that can have the value oss alsa sdl esd pa fmod. I really believe that
OSS support only is not a good idea, and that ALSA, Pulse Audio, SDL and
ESD support would be good. Are they activated by default?

4- Is this normal, and could it be avoided:

dpkg-shlibdeps: warning: dependency on libm.so.6 could be avoided if
"debian/xen-qemu-dm-3.4/usr/lib/xen-3.4/boot/qemu-dm" were not
uselessly
linked against it (they use none of its symbols).
dpkg-shlibdeps: warning: dependency on libXext.so.6 could be avoided if
"debian/xen-qemu-dm-3.4/usr/lib/xen-3.4/boot/qemu-dm" were not
uselessly
linked against it (they use none of its symbols).

I really need these answers before the upload of my Debian package, that
by the way, works already.

-lm is needed for hw/fmopl.c.  It shouldn''t be any harm to always have
it however, since that''s from libc.

qemu doesn''t link it itself.  It''s probably a spurious
Requires in some
/usr/lib/pkgconfig/*.pc that should actually be a Requires.private.

On xen-unstable the path is /etc/xen/scripts/qemu-ifup by default.

It is meant to provide a network block device, something like using a
file as disk image over NFS.
I don''t think anyone is using or testing this tool in the xen
community,
therefore I wouldn''t package it.

nope

you can pass additional command line parameters to xen-setup and they
will be passed to the configure script automatically
