Indeed you are right, the current help is bad. It used to be like this
(source destination) but because most people will use "/" as source
anyway that is the default now and only destination needs to be
specified. apt-lone clone --help will show it correctly:
$ apt-clone clone --help
usage: apt-clone clone [-h] [--source SOURCE] [--with-dpkg-repack]
[--with-dpkg-status]
destination
positional arguments:
destination
optional arguments:
-h, --help show this help message and exit
--source SOURCE
--with-dpkg-repack add no longer downloadable package to the state
bundle
(that can make it rather big)
--with-dpkg-status include full copy of dpkg-status file, mostly
useful for
debugging
But obviously this needs correcting in the main help text too.

Indeed. Because this makes the clone archive usually really big its
not done by default. It needs "--with-dpkg-repack" on the
commandline. I added a note about this now to the output if this
option is not given.

It should do, indeed. Its just that the commandline switch is a bit
hidden.

No, it should not be expected from the user. The envisioned workflow
is:
$ apt-clone clone /tmp/mybox
$ sudo apt-clone restore /tmp/mybox.apt-clone.tar.gz
--destination=/tmp/test-chroot
(or no --destination then it will simply use the main system instead
of creating a chroot and cloning the system there).
I commited some improvements to the text now to:
http://bazaar.launchpad.net/~ubuntu-core-dev/apt-clone/trunk/revision/85?start_revid=85
Feedback is welcome.
Thanks,
