-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.

+.IP \fBpersistence\fP 4
+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 \fIlive\-persistence.conf\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.ext4" and
+"home\-sn.squashfs".
+.IP "\fBpersistence\-encryption\fP=\fITYPE1\fP,\fITYPE2\fP ... \fITYPEn\fP" 4
+This option determines which types of encryption that we allow to be used
+when probing devices for persistence 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".
+.IP \fBpersistence\-media\fP={\fIremovable\fP|\fIremovable\-usb\fP} 4
+If you specify the keyword 'removable', live\-boot will try to find
+persistence and snapshot partitions on removable media only. Note that if
+you want to further restrict the media to usb mass storage only, you can use
+the 'removable\-usb' keyword.
+.IP "\fBpersistence\-method\fP=\fITYPE1\fP,\fITYPE2\fP ... \fITYPEn\fP" 4
+This option determines which types of persistence media we allow. If
+"overlay" is in the list, we consider overlays (i.e. "live\-rw" and
+"home\-rw"); if "snapshot" is in the list, we consider snapshots
+(i.e. "live\-sn" and "home\-sn"). The default is "overlay,snapshot".
