[Bug 1625023] Re: switch to systemd on ubuntu phone xenial

[Vicamo Yang]

** Description changed:

  Snappy heavily rely on systemd system session and xenial has systemd by
  default.
  
  [steps to construct systemd-based avila]
  
  1. flash images built from xenial branch [1]. This should gives a
  working xenial+upstart avila. Following steps are based on rootfs rev
  51.
  
- 2. Install systemd-sysv rather than upstart-sysv (Bug 1625023)
- 2.1. rebuild latest ubuntu-touch package from source [2] with patch [3] applied.
- 2.2. download latest systemd-sysv package [4].
- 2.3. dpkg -i ubuntu-touch_*.deb systemd-sysv_*.deb
+ 2. Reboot into recovery mode and manually change upstart-local-bridge service type to simple.
+ host$ adb shell
+ device# mkdir ubuntu
+ device# mount /dev/block/platform/mtk-msdc.0/by-name/system ubuntu
+ device# exit
+ host$ adb pull /ubuntu/lib/systemd/system/upstart-local-bridge.service .
+ (edit the file as mp[2] does ...)
+ host$ adb push upstart-local-bridge.service \
+   /ubuntu/lib/systemd/system/upstart-local-bridge.service
+ host$ adb shell
+ device# sync; sync; sync
+ device# umount /ubuntu
+ device# exit
+ host$ adb reboot
  
- 3. Install android-tools-adbd for systemd (Bug 1627613)
- 3.1. Install prebuilt package [5] or recompile it from source [6] with patch [7] applied.
- 3.2. Install the package from Terminal app because it will break adb connection and interrupt the installation process leaving a very bad state of the package.
- 
- 4. Recompile upstart with merge proposal [8] include and install at
- least the built binary /sbin/upstart-local-bridge.
- 
- 5. Reboot.
+ 3. Go to Settings::About page to enable developer mode.
