'''Build a system, outside of a system branch.
Command line arguments:
* `REPO` is a git repository URL.
* `REF` is a branch or other commit reference in that repository.
* `FILENAME` is a morphology filename at that ref.
You probably want `morph build` instead. However, in some
cases it is more convenient to not have to create a Morph
workspace and check out the relevant system branch, and only
just run the build. For those times, this command exists.
This subcommand does not automatically commit changes to a
temporary branch, so you can only build from properly committed
sources that have been pushed to the git server.
Example:
morph build-morphology baserock:baserock/morphs \
master devel-system-x86_64-generic

def build(self, args):
'''Build a system image in the current system branch
Command line arguments:
* `SYSTEM` is the name of the system to build.
This builds a system image, and any of its components that
need building. The system name is the basename of the system
morphology, in the root repository of the current system branch,
without the `.morph` suffix in the filename.
The location of the resulting system image artifact is printed
at the end of the build output.
You do not need to commit your changes before building, Morph
does that for you, in a temporary branch for each build. However,
note that Morph does not untracked files to the temporary branch,
only uncommitted changes to files git already knows about. You
need to `git add` and commit each new file yourself.
Example:
morph build devel-system-x86_64-generic
