Idea for command: purge-kernels

[Reuben Thomas]

Old kernels are (with good reason) kept installed by default, but
until such time as there's an official solution (e.g. allow them to be
purged once a new kernel has been running for some days), it would be
nice to be able to purge them manually without having to name the
packages.

Good idea; what do you suggest the subcommand to be? PURGE-OLD-KERNELS maybe?

Regarding the exact workings, what happens if, say, one has installed
in the past amd64, i386, and rt-amd64 kernels for example? Do we leave
those lying around? What about the custom-built one, which may have
funny names?

purge-old-kernels is better than my suggestion (purge-kernels).

I suggest not trying to cover any of the complex cases: they won't
apply most of the time (so not much time saving) and are likely to be
easy to mess up.

So, which of the cases I mentioned do you consider complex? I need to
know how to filter, for example. Maybe you can provide a patch, for
then we know exactly what you want, without this back-and-forth.

Great idea!

I hadn't really thought how it would be implemented, to be honest. I
think the simplest thing is "apt-get remove all linux-image packages
apart from the most recent and/or running one". That doesn't cover the
case of non-Linux kernels, and I still don't know how to express that
in apt-speak.

How about :
$ wajig purgeoldkernel n

Where n defaults to 1 - to keep one extra kernel - so you end up with the running kernel and one
older to fall back on.
