Bug#808721: libc: avoid negative questions in restart-without-asking debconf knob

[Daniel Shahaf <danielsh@apache.org>]

Package: libc6
Version: 2.21-4
Severity: minor

Dear Maintainer,

The restart-without-asking debconf knob is formulated as a negative question:

    Template: libraries/restart-without-asking
    Type: boolean
    Default: false
    _Description: Restart services during package upgrades without asking?

This can be confusing: in my case, I initially thought I should pick "yes"
since I read the question is "would you like to be prompted before restarting
services".

I suggest to change the description to:
..
    _Description: Ask permission to restart services during package upgrades?
..
and accordingly change the default answer to "Yes" (which would not be
a semantic change).

I assume this could be done backwards-compatibly by defining a new knob
(restart-without-asking2) and looking for the current knob name if the new knob
isn't set.

Cheers,

Daniel
