List (on stdout) all partitions with names among LABEL(s) that are compatible
with live-boot's overlay persistence, and that are adhering to live-boot's
persistence filters (e.g. persistence-media). If no LABEL is given the default
in live-boot is used ('${custom_overlay_label}').

Activates persistence on the given VOLUME(s) (specified via block device).
Successes and failures are written to stdout. There are no checks for whether
the given volumes adhere to live-boot's options.

Deactivates persistence on the given VOLUME(s) (specified via block device).
