[Bug 1451565] Re: /var/log owned by wrong group (android_input) (again)

[Selene Scriven]

Additionally, the permissions of /var/log aren't the only thing which
change when re-flashing the same image.

I collected the output of 'ls -alR /' during the first and second flash,
filtered it a bit to remove most of the noise, and diff'd the two to
look for differences.  Some of the results are unusual.

One oddity is a change in mmcblk0 partition numbers, though this might make sense if the system swaps between two as a failsafe mechanism.
 /dev/disk/by-path:
-lrwxrwxrwx root root platform-mtk-msdc.0 -> ../../mmcblk0boot1
+lrwxrwxrwx root root platform-mtk-msdc.0 -> ../../mmcblk0boot0
...
-lrwxrwxrwx root root 57f8f4bc-abf4-655f-bf67-946fc0f9f25b -> ../../mmcblk0p14
+lrwxrwxrwx root root 57f8f4bc-abf4-655f-bf67-946fc0f9f25b -> ../../mmcblk0p15

More unusual is an apparent difference in the version numbers of installed click apps.  For example:
 /sys/kernel/security/apparmor/policy/profiles:
-drwxr-xr-x root root com.canonical.cincodias_CINCODIAS_0.2.19
+drwxr-xr-x root root com.canonical.cincodias_CINCODIAS_0.2.20
-drwxr-xr-x root root com.canonical.elpais_webapp-ELPAIS_0.6.28
+drwxr-xr-x root root com.canonical.elpais_webapp-ELPAIS_0.6.29
-drwxr-xr-x root root com.canonical.scopes.bbc-sport_bbc-sport_1.3.1.31
+drwxr-xr-x root root com.canonical.scopes.bbc-sport_bbc-sport_1.3.1.32
-drwxr-xr-x root root com.ubuntu.calculator_ubuntu-calculator-app_2.0.155.32
+drwxr-xr-x root root com.ubuntu.calculator_ubuntu-calculator-app_2.0.155.31
-drwxr-xr-x root root com.ubuntu.music_music_2.1.857.13
+drwxr-xr-x root root com.ubuntu.music_music_2.1.857.12
-drwxr-xr-x root root com.ubuntu.scopes.youtube_youtube_1.0.18-134.30
+drwxr-xr-x root root com.ubuntu.scopes.youtube_youtube_1.0.18-134.28
-drwxr-xr-x root root com.ubuntu.weather_weather_1.1.403.20
+drwxr-xr-x root root com.ubuntu.weather_weather_1.1.403.19

And of course the known symptom:
 /userdata/system-data/var/log:
-drwxrwxr-x root syslog .
+drwxrwxr-x root android_input .
--rw-r----- syslog adm auth.log
--rw-r----- syslog adm syslog

The filtered 'ls' output and diff are attached.

Title:
  /var/log owned by wrong group (android_input) (again)

Status in livecd-rootfs package in Ubuntu:
  Confirmed

Bug description:
  Bug 1425529 (or bug 1425869) is back.  No syslog on arale image 31 and
  krillin vivid 188 (which are about two weeks apart), and possibly on
  other builds too.  I'm not sure how widespread it is, but I've run
  into this several times lately.

  Sorry for the dupe, I was asked to create a new bug for it instead of
  re-opening one of the previous two.
