-.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
+.IP \fBpersistence\-subtext\fP=\fISUFFIX\fP 4
+Add a suffix when searching for the image filenames or partition labels to
+use for the above mentioned persistence 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
+persistence storage choices.
