Allow using non-relative paths as identifiers #21
Description
I would like to be able to set certain directories to be shared between users, such as for example Steam games which by default is located in ~/.local/share/Steam/steamapps/, though currently there doesn't seem to be support other than messing with ../../../ in the identifier.
I suggest that paths that are prefixed with / do not get a relative path, and instead works from the root directory, so something like m d .steam/share/Steam/steamapps /<shared_directory>/steamapps. I'm not sure if it's currently the case, but it would be useful if this could be formated the same way as FILELAYOUT.
