Bug description:
[ SRU Justification ]
Not only is this behaviour broken for every day use, but it also completely
breaks livefs generation for ubuntukylin, and causes most of $flavour-desktop
to be on the autoremove list in any point release livefs, making this bug
point-release critical.
[ Test Case ]
Install a metapackage (say, ubuntu-standard), and then "apt-get --purge
autoremove ubuntu-standard" and check that only that package is removed, rather
than large chunks of its dependencies.
Further, also run the test case from comment 2 of bug #1429041 and
make sure the previous fix didn't regress.
[ Regression Potential ]
My fix was tested locally against both test cases and passes with flying
colours, so I don't see how this can make things any worse than they already
are.
[ Original Report ]
In current trusty, vivid, and wily, when you install ubuntu-minimal (from the
"metapackages" section) in a clean chroot, some 75ish packages are installed.
If you then "apt-get --purge autoremove ubuntu-minimal", some large portion
(between 20 and 40, depending on the target release) of those dependencies are
removed again.
If this test is repeated putting the release pocket version of
apt/libapt on hold, the purge/autoremove only removes the metapackage,
but none of its dependencies, so this is likely a regression brought
on from the previous autoremoval fix.
This bug is release-critical for the 14.04.3 point release, as we
install using metapackages instead of tasks in point releases, thus
meaning that anyone removing ubuntu-desktop for any reason will end up
with dozens (potentially hundreds) of packages on the autoremoval
list.
