[Bug 1637797] Re: kernel referred to by /*.old autoremoved

[Marius Gedminas]

One interesting thing is that this bug didn't manifest on other Ubuntu
14.04 LTS servers.

I've a couple of sibling servers that are supposed to be exact copies
(one is a hot standby for the other).  One of them is now down to just
one kernel, with two kernels listed in /etc/apt/apt.conf.d/01autoremove-
kernels.  The other has two kernels left, but it has *three* kernels
listed in /etc/apt/apt.conf.d/01autoremove-kernels.

In both cases some of the kernels listed in APT::NeverAutoRemove did get
removed.
