-"This option determines which types of encryption that we allow to be used "
-"when probing devices for persistent media. If \"none\" is in the list, we "

+"live-boot will probe devices for persistence media. These can be partitions "
+"(with the correct GPT name), filesystems (with the correct label) or image/"
+"archive files (with the correct file name). Overlays are labeled/named "
+"either \"full-ov\", which will be mounted on /, or \"custom-ov\", which can "
+"be completely customized (see I<live-persistence.conf>(5)); snapshots are "
+"labeled/named either \"live-sn\" or \"home-sn\" and will be extracted into / "
+"or /home, respectively (see I<live-snapshot>(1) for more information). The "
+"order these are handled are: full-ov, custom-ov, live-sn, home-sn. Overlay "
+"image files and snapshot archive files have extensions which determines "
+"their filesystem or archive type, e.g. \"custom-ov.ext4\" and \"\\home-sn."
