This is a followup to f7f292d359e0eb77617f4ecf6b3164f868ec1784. * doc/guix.texi (Preparing for Installation): Give commands for encrypted root installation. (Proceeding with the Installation): Add item about mapped devices. (File Systems): Mention that 'dependencies' can list <mapped-device> objects. * gnu/system/examples/desktop.tmpl (mapped-devices): New field. (file-systems): Add 'dependencies' field.
