-.IP \fBpersistent\-subtext\fP=\fISUFFIX\fP 4
-Add a suffix when searching for the image filenames or partition labels to
-use for the above mentioned persistent feature, the SUFFIX will be added
-after a dash (e.g.: "live\-sn" would transform to "live\-sn\-SUFFIX"). This is
-handy to test multiple live\-boot based live\-systems with different
-persistent storage choices.
-.IP {\fBpreseed/file\fP|\fBfile\fP}=\fIFILE\fP 4
-A path to a file present on the rootfs could be used to preseed debconf
-database.
-.IP \fBpackage/question\fP=\fIVALUE\fP 4
-All debian installed packages could be preseeded from command\-line that way,
-beware of blanks spaces, they will interfere with parsing, use a preseed
-file in this case.
+.IP \fBpersistence\-read\-only\fP 4
+Filesystem changes are not saved back to persistence media. In particular,
+overlays and netboot NFS mounts are mounted read\-only.
+.IP "\fBpersistence\-storage\fP=\fITYPE1\fP,\fITYPE2\fP ... \fITYPEn\fP" 4
+This option determines which types of persistence storage to consider when
+probing for persistence media. If "filesystem" is in the list, filesystems
+with matching labels will be used; if "file" is in the list, all filesystems
+will be probed for archives and image files with matching filenames. The
+default is "file,filesystem".
+.IP \fBpersistence\-label\fP=\fILABEL\fP 4
+live\-boot will use the name "LABEL" instead of "persistence" when searching
+for persistent storage. LABEL can be any valid filename, partition label, or
+GPT name. This option replaces the less flexible persistent\-subtext option
+from version 2 of live\-boot. If you wish to continue using legacy names for
+persistent storage, use the full name with this option,
+e.g. persistence\-label=live\-rw\-foo
