-live\-boot will probe filesystems for persistent media. These can either be the filesystems themselves, if labeled correctly, or image/archive files, if named correctly. Overlays are labeled/named either "live\-rw" or "home\-rw" and will be mounted on / or /home, respectively; snapshots are labeled/named either "live\-sn" or "home\-sn" and will be extracted into / or /home, respectively (see live\-snapshot(1) for more information). Overlays are mounted before snapshots are extracted, and for both overlays and snapshots, "live\-*" are handled before "home\-*". Overlay image files and snapshot archive files have extensions which determines their filesystem or archive type, e.g. "live\-rw.ext3" and "\home\-sn.squashfs".
+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\fR(5)); snapshots are labeled/named either "live\-sn" or "home\-sn" and will be extracted into / or /home, respectively (see \fIlive\-snapshot\fR(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".
