.user_wants_to_use_key_already_in_gas?(uid = '') ⇒ Boolean

If the user says ‘f’, the system will

report that there isn't an id_rsa already in gas.  This causes a new key to overwrite automatically down the road.

This is for checking if a .gas/rsa file already exists for a nickname which is being registered If the rsa exists, then we’re goona need to ask if we should use it, or if we should delete it

Returns true to indicate that the user would like to use the rsa file already in .gas () Returns false when there are no naming conflicts.

Returns:

  • (Boolean)

if it does, it asks the user if they would like to use that as their ssh key, instead of generating a new key pair.
