Bug#867282: live-wrapper: Lacks dependency on squashfs-tools

[Jeff Epler <jepler@unpythonic.net>]

Package: live-wrapper
Version: 0.6+nmu1
Severity: serious
Justification: Policy 3.5

Dear Maintainer,

Hi.  after installing live-wrapper with --no-install-recommends, it does
not function properly, eventually issuing an error that /tmp/.../live
can not be found.  I believe that this is because it does not depend
on squashfs-tools to provide the "mksquashfs" program.

This dependency bug is often not visible, because "mksquashfs" is a
recommends, but not a depends, of vmdebootstrap.

Specifically, I created a new stretch schroot, then inside it I ran 'apt
install live-wrapper --no-install-recommends', and then 'lwr'.  The
eventual failure looked something like this:
      File "/usr/lib/python2.7/dist-packages/lwr/vm.py", line 66, in detect_kernels
        filenames = os.listdir(os.path.join(cdroot, "live"))
    OSError: [Errno 2] No such file or directory: '/tmp/tmpZDO8j6/live'

Thanks for your attention to this matter,
Jeff
