Robert Church 4dc4fb11a7 debian: Remove installer code used for initial integration
Remove two patches that were initially submitted to enable AIO
integration prior to the creation of the Debian kickstarts. Now that we
are utilizing the kickstart file and LAT kickstart hooks, remove the
unused code from the installer.

This change also renames patches in sequential order and cleanups up
subject lines.

Test Plan:
PASS: Install/Bootstrap/Provision AIO
PASS: Install/Bootstrap/Provision STD Controller/Worker

Subject: init-ostree-install.sh: break hardlinks in /var
Here the root filesystem is managed by OSTree. OSTree is designed to
manage/deploy read-only filesystem. For read-only filesystem, hardlink
all files with same content is safe and can save disk space. It is a
good principle for readonly folders like /bin, /lib and so on. While
"/var" is somehow special that it is designed to store variable data
files, it can not be read-only, it must be read-write. Files in
"/var" should not be hardlinked together like other folders, break
them to make it.
Do the same for /usr/homedirs/home as it gets mounted at /var/home
at runtime.
