Bug#691338: libconfig-model-perl: Bad handling of default setting in CheckList breaks libconfig-model-openssh's demo

[Dominique Dumont]

Package: libconfig-model-perl
Version: 2.021-3
Severity: normal

Dear Maintainer,

The new mechanism to check whether to write or not a config file is
broken for checklist. When a default checklist is specified,
config-model should write back the file. But this change is currently
not detected.

OpenSsh model use a lot these checklist and is broken. This bad
behavior is shown by the demo program
(i.e. /usr/share/doc/libconfig-model-openssh/perl/examples/user-demo.pl)

I'm preparing a minimal patch to fix this issue.

All the best
