[Bug 90085] Re: When /tmp is mounted noexec, preconfigure fails

[Jeff]

On Ubuntu 18.04 with noexec on /tmp running 'apt-get install -y selinux'
and then doing a required reboot will give you a non-booting host.

As an aside, the same security guidance (CIS Benchmarks for one) about
noexec on /tmp should be applied to /var/tmp, so changing
APT::ExtractTemplates::TempDir to "/var/tmp"; isn't really an option
here in the long run.
