xymon-client and snaps, client report gets red in disk, inode, misc states

disk and inode checks are from the xymon package, the misc check is indeed from hobbit-plugins.

Instead of looking at parts of the mount-point path, I implemented the exclusion in both packages by completely ignoring squashfs mounts as these are always read-only since it's a read-only file system. That way we might also catch similar cases with other container formats which also use squashfs.

Thanks for the bug report!

This bug was fixed in the package hobbit-plugins - 20181101

---------------
hobbit-plugins (20181101) unstable; urgency=medium

  * libs.yaml:
    - Whitelist "/memfd:" pseudo files (used by at least pulseaudio and
      Xorg) causing false positive. Thanks Alex Myczko for the report!
    - Whitelist "/var/lib/nfs/etab". Thanks Alex Myczko for the report!
  * Declare compliance with Debian Policy 4.2.1.
    + misc.d/zombies: Use "#!/usr/bin/perl", not "#!/usr/bin/env perl".
  * Ignore squashfs mounts for misc.d/mount-ro check. (LP: #1798557)
  * Add build-dependencies on libdate-parse-perl + liblist-moreutils-perl
    to fix failing tests and FTBFS. (Closes: #912104) Thanks Adrian Bunk!
  * backuppc:
    + Refactor code to make it more readable and use modern perl features.
    + Add options for hosts which should always cause a alert or always
      only cause a warning independent of the severity of the error.

    building again, but restrict it to override_dh_auto_build and the
    server's install target in override_dh_auto_install.
  * Fix URL pointing upstream mailing list posting in
    debian/xymon.lintian-overrides. It was pointing to the wrong mail.
  * Make lintian overrides for package-contains-hardlink more generic:
    + Catches future CGI script hardlinks.
    + Independent of which file is regarded as file others are linked to.
    + Reduces amount of lines needed in debian/xymon.lintian-overrides.
  * Ignore squashfs mounts when checking for disk usage. (LP: #1798557)

    Fixes lintian warning FSSTND-dir-in-manual-page.
  * Fix existence of debian/docs together with debian/xymon.docs and
    debian/xymon-client.docs by adequately merging the former into the two
    latter files. Reintroduces some upstream documentation which was
    missing for a few years.
