[one-users] storage configured for nfs, using scp

[Javier Fontan]

Hello,

Deployment file is always copied using scp to the remote node. It is a
little file (no more that 5 Kb, usually a lot less) so it wont affect
a lot in the performance. It is done this way so it works for shared
and non-shared installations. The bulk of movements, that is, the
images, are moved using cp over nfs if you use nfs driver.

Bye
