Sorry about that, was not aware about the anti spam problems.

I think another problem with starting wpa_supplicant before the
filesystem is up is that it uses /var/run where it should use /run. Do
you think you (or somebody else) will be interested in doing that? If
so, should I file a new bug?

I do not think it blocks boot on async systems (at least when NFS is
not used) like Upstart or systemd.
