Standards 4.1.3 and apt-cacher

[Mark Hindley <mark@hindley.org.uk>]

Hello,

I am trying to upgrade apt-cacher to Standards version 4.1.3. In particular
using DISABLED=yes|no in /etc/defaults is now prohibited.

apt-cacher can be run as a daemon or from /etc/inetd.conf and this configuration
is set in response to a debconf question.

I have a working version of the postinst which I believe complies with the new
policy by no longer changing a value in /etc/default/apt-cacher, however it
contains multiple calls to update-rc.d (one to register the init file and then
calls to enable/disable as appropriate in response to db_get). This produces the
lintian error: duplicate-updaterc.d-calls-in-postinst.

Is my approach flawed or is lintian being overzealous?

Any other suggestions?

A pruned version of postinst is below.

Thanks for your help.

If you are operating legacy CGI mode, this is deprecated and you really should
consider changing to one of the daemon modes. See cgi_advise_to_use and
cgi_redirect in man apt-cacher(8) for help in redirecting your clients.

To change your choice, run 

  dpkg-reconfigure apt-cacher
