+"container image as device" contains meeningfull whole APFS container (including Preboot, Recovery, VM).
+However, this type of image has no partition map information and volume title information.
+So, "asr imagescan" and "asr restore" goes to fail.
+We have to mount image first by "hdiutil attach", then use "asr restore" command.
+
+When we do this process in booted by macos USB installer, "asr restore"'s last process will be fail.
+Because last process is inverting APFS container process, but, macos USB installer has no apfs_invert command.
+We need do this process in standard installed macos system or inject apfs_invert to macos USB installer's BaseSystem.dmg.
