Comment 2 for bug 1686138

Judging from the open bug reports, purge-old-kernels also does the wrong thing in various situations currently.

To make progress, can I suggest a deprecation plan?

1) Mark purge-old-kernels as planned to be deprecated in Artful. Work as normal anyway, but note the planned deprecation to stderr, suggesting "apt autoremove" instead. Invite bug reports in that message (and state a location for them).

2) Address any bugs that get reported. At least this way we'll have open bugs for any problems in "apt autoremove", rather than the current situation where it is claimed to be problematic with no known bugs open.

3) After a period of time after no new reports, remove purge-old-kernels from the byobu in the development release (perhaps B or C).

4) I'm not suggesting any change to previous releases. purge-old-kernels will continue to work in 12.04, 14.04 and 16.04.
