-live\-boot will look for persistent and snapshot partitions or files labeled
-"live\-rw", "home\-rw", and files called "live\-sn*", "home\-sn*" and will try
-to, in order: mount as /cow the first, mount the second in /home, and just
-copy the contents of the latter in appropriate locations
-(snapshots). Snapshots will be tried to be updated on reboot/shutdown. Look
-at live\-snapshot(1) for more informations.

-If "nofiles" is specified, only filesystems with matching labels will be
-searched; no filesystems will be traversed looking for archives or image
-files. This results in shorter boot times.

-If "cryptsetup" is specified, filesystems stored on Luks\-encrypted devices
-will be considered as well as others when searching for a persistence
-filesystem; the user will be prompted for any needed decryption passphrase.

+live\-boot will probe devices for persistent 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 \fIlive.persist\fP(5)); snapshots are labeled/named
+either "live\-sn" or "home\-sn" and will be extracted into / or /home,
+respectively (see \fIlive\-snapshot\fP(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.ext3" and "\home\-sn.squashfs".

+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
+allow unencrypted media; if "luks" is in the list, we allow LUKS\-encrypted
+media. Whenever a device containing encrypted media is probed the user will
+be prompted for the passphrase. The default value is "none".
