Squid & DansGuardian block upgrading to BIG-sized local_vars.yml

[holta]

Expected behavior and actual behavior.

./iiab-install fails in either of these 2 ways:

TASK [network : Enable DansGuardian] *******************************************
fatal: [127.0.0.1]: FAILED! => {"changed": false, "failed": true, "msg": "Could not find the requested service dansguardian: host"}

or

TASK [network : Enable Squid service] ******************************************
fatal: [127.0.0.1]: FAILED! => {"changed": false, "failed": true, "msg": "Could not find the requested service squid: host"}

Steps to reproduce the problem.

Run "./iiab-install --reinstall" after upgrading a standard install from MEDIUM-sized local_vars.yml to BIG-sized local_vars.yml.

This same problem occurred when upgrading a MIN-sized local_vars.yml to BIG-sized.

some people sincerely believe that Squid and DansGuardian should both be deprecated. Which may well be a thoughtful + constructive way forward to focus on more modern grassroots use cases. In any case, we'll discuss different perspectives on Bit Rot versus Wise Metrics For Amputation (etc) during our Monday community/team call @ http://minutes.iiab.io -- so we're not shooting ourselves in the foot with nearly perpetual maintenance of rarely use packages.

Upgrading post install has always been problematic that is why in the past it was the kitchen sink approach with no option not to install some services while default_vars just lied about being able to do so, just leaving the services disabled. Now with the slimmed down installs in place moving to big should really be a install time option by starting with "big" or "from scratch". There is no issue if you start with the services to be installed from the start, and with a bit of jiggling I can restore the selective post install option, I'm debating if it's worth the effort.

The fix is in #508 f4c0e3b posted long before this issue was recorded.

Apparently fixed. We can re-open if nec.
