Comment 5 for bug 1699913

@Tianon,

You are correct that a user then would inevitably get an out of date package.

However, removing the release pocket content
a.) means every user in every image has to download that data which does not change.
b.) only defers the potential problem until later.

Essentially, the problem is that in order to *ever* run:
  apt-get install package
you have to have run recently run "apt-get update" for some value of recently.

default cloud images (I believe) end up running apt-get update within 24 hours and
then do so on a daily-ish basis, which probably suffices as a definition of
"recently".

I think the ideal solution is to have 'apt-get install' (or 'apt install') to
run an update by default if it detects that sources are out of date or modified.
