I know that userspace is a little bit too "high level" for me but
please, don't call me stupid. I've heard that azure was 64bit only (I've
no link, sorry) and also someone told me he didn't managed to boot i386
debian on azure while amd64 version worked nicely. The only remaning
possibility would be kernel 64bit+32bit userspace but it may leads to
bugs due to missing/buggy ioctl32 compat and I guess that installing
such a thing is not for random dev/admin so they would probably now how
to handle that.

oh. weird. I was assuming that the lack of registration in azure
(because there's no agent for freebsd) would kill the vm sooner or
later. The "privisionning" issue on this page may be related to missing
agent.

If you manage to get this working, I'll change it back to arch: all :)

Tests are one thing, reality an other. If I use debootstrap, I'll get
net-tools. So, how can you have a system without it ?
Anyway, I've added the dep on my git tree.

To be clearer, if you use uninstall, it'll remove stuff like
/var/lib/waagent which contains machine specific data (provisionning
datas) and sudoers infos. If you remove this, the vm will loose its ids.
This has been experienced by people on ubuntu:
