Yes, always from the master branch. Since LXD is very young and not
supported (until 16.04), we can do this. Then I think we'll move to a
lxd-1.0 branch and cherry-pick relevant fixes from master to that to
release 1.1, etc. while we work on 2.0 (this is the same as lxc does
today); much like the kernel model. Having separate "dev" and "stable"
branches just confuses things IMO.
