Public bug reported:
[SRU Justification]
Up until artful, console-setup declares a versioned dependency on
initramfs-tools. This was an Ubuntu-specific dependency only needed for
upgrades, and the version referenced is ancient (ca. 2008). In artful and
later, the dependency has now been removed.
Since this is no longer relevant for upgrades and we would not otherwise
have a dependency on initramfs-tools, we should drop this dependency to
support building of images with initramfs-tools removed for systems that
we know don't require an initramfs.
[Test case]
1. On a xenial default cloud image install, try to run 'sudo apt purge
initramfs-tools'.
2. Verify that this tries to remove console-setup, console-setup-linux, and kbd.
3. Cancel the removal.
4. Install console-setup from xenial-proposed.
5. Run 'sudo apt purge initramfs-tools' again.
6. Verify that console-setup, console-setup-linux, and kbd are not removed.
7. Run 'sudo apt install --reinstall console-setup' and confirm that the
package can be installed successfully without initramfs-tools installed.
[Regression Potential]
If a user needs an initramfs in order to mount their root device, and
console-setup is the only package on their system which depends on
initramfs-tools, it is possible that the user may remove initramfs-tools and
render their system unbootable.
This is unlikely because initramfs-tools is still part of the 'minimal'
seed and is therefore a dependency of ubuntu-minimal; and it remains a
dependency of the generic kernel image.
