  - The *machineid* module, which generates UUIDs for systemd and dbus
    and can generate entropy files (filled from `/dev/urandom` in the host
    system) now supports more than one entropy file; generate them as needed

+ - Progress reporting from the *unpackfs* module has been revamped:
+   it reports more often now, so that it is more obvious that files
+   are being transferred even when the percentage progress does not
+   change.
+ - The *unpackfs* module now supports a *weight* setting for each
+   of the unpack entries. For a single entry this does not matter,
+   but if there are multiple entries it allows tweaking the relative
+   progress between each entry.
