> For Debian 7 "Wheezy" LTS there will be no requirement to add a separate wheezy-lts suite to your sources.list any more. In fact you will not notice the switch to LTS because after the official security support by the Debian Security Team ends, security updates will be provided via security.debian.org 's wheezy/updates.

This stops us from erroneously adding "squeeze-lts" to "oldstable" which is now "wheezy", not "squeeze" (but "oldoldstable" _is_ squeeze, hence the new check on `/etc/debian_version` being `6.*` instead, and done as a `case` for the eventual addition of `wheezy-lts`, etc).

This makes APT be appropriately aggressive about removing packages it added due to `Recommends` or `Depends` if the packages they were added for are removed (even if other packages only have the softer `Suggests` relationship).

Instead of applying it only for the final `chroot`, this adds a chroot helper function to apply it appropriately for every chroot, including making sure that we find `chroot` in our current host `PATH` in case it's in a strange place.

when running in the chroot, it would be expected to have a Debian-ish environment,
most important the PATH variable. Otherwise the host PATH would be used which can wrong
for Debian, especially if the host is Arch (which doesn't have /bin, /sbin or /usr/sbin).

This file is one APT creates to make sure we don't "autoremove" our currently in-use kernel, which doesn't really apply to debootstraps/Docker images that don't even have kernels installed.

Later versions of `apt` are smart enough to just create this directory if it's missing, but Lucid balks (just like `gnupg` and `gpgv` aren't in the Required set so don't come in a minbase -- good ol' Lucid).

This results in a dramatic improvement in the size of individual "apt-get update" layers (on a clean wheezy base, from "29.88 MB" down to "8.273 MB").

Note that the archive does _not_ have a symlink from oldstable-lts to squeeze-lts, hence the change from using "${suite}" to not using it in here and just using the string "squeeze-lts" directly regardless of whether we're building a "squeeze" image or an "oldstable" image.

These new scripts are streamlined such that, for example, "contrib/mkimage/debootstrap" is _only_ responsible for filling a directory with the results of running debootstrap, and it can accept any arbitrary arguments.
