[Fab-user] Putting a local file owned by root?

[Simpson Lachlan]

I'm trying to use Fabric to deploy SLURM on new worker nodes.

As part of this process, I need to copy a file from the head node (with 
fabfile) to the worker node. The file is owned by root locally.

I started out with
    put('/etc/munge/munge.key', '/etc/munge/munge.key', use_sudo=True, 
mirror_local_mode=True)
but I think I've just discovered that use_sudo=True is a reference to the 
remote, not the local.

Then I found some discussion around 
    with settings(user='<username>'):
so I tried that wrapped around the put, with username=root, and this failed 
when the login prompt asked for a non existent root password on the remote 
server.

How can I run a local sudo user?

Am I asking too much - should I build it part by part? (ie, use local to cp 
file to user's ~/tempfile.key, put file, adjust remote perms, use local to 
remove temp file)
