== Summary ==
Split the tzdata package into two parts - tzdata and tzdata-minimal.
tzdata will require tzdata-minimal. tzdata-minimal provides the
minimal files needed to support UTC on containers.

== Detailed Description ==
This is the first step towards providing support for a minimal, UTC
only, version of tzdata for containers. The tzdata-minimal package
will be a stand-alone, UTC only, subset of tzdata. The tzdata package
will require tzdata-minimal.
With this framework in place, other packages can develop code to
detect a minimal tzdata installation. These packages will also need
to provide appropriate messages when users request timezone
information not available when only tzdata-minimal is installed.
In general, I like the idea of making it easier to not install tzdata.
For many machines it's completely unnecessary, and 5MB is enough to
make this worthwhile.
I don't know enough about all the consumers to comment on the details.
FWIW, systemd-timedated already has a reasonable message that encompasses
both possible errors:
$ timedatectl set-timezone Europe/Warsaw2
Failed to set time zone: Invalid or not installed time zone 'Europe/Warsaw2'
But I think it'd be useful to use a different message if we can
distinguish the two cases. I'd be happy to take a patch...
