Okay, figured out what the issue is. The "cat /proc/self/cgroup" needs
to be run from the terminal application on the device, not a terminal on
a host device. The terminal app on the device is in a cgroup, as it's
launched by UAL, but the adb shell is not as it's handle by a system
service.

Title:
terminal doesn't appear on the freezer cgroup
Status in Ubuntu Application Launcher:
Invalid
Bug description:
Found while testing silo #28 on krillin 14.09 proposed #89.
This is what I get when the terminal is running:
phablet@ubuntu-phablet:~$ cat
/proc/self/cgroup4:name=systemd:/user.slice/user-32011.slice/session-2.scope
3:freezer:/user.slice/user-32011.slice/session-2.scope
2:cpuacct:/user.slice/user-32011.slice/session-2.scope
1:cpu:/user.slice/user-32011.slice/session-2.scope
Steps to reproduce from the test plan:
https://wiki.ubuntu.com/Process/Merges/TestPlan/ubuntu-app-launch
Launch the Terminal app
A new application should open with a terminal prompt where you can
type commands
Ensure the Terminal is in a terminal specific cgroup
Type the command cat /proc/self/cgroup
Under the "freeze" cgroup the end of the path should include the
AppID of the terminal. An example would be (the version many change):
4:freezer:/user.slice/user-32011.slice/session-c2.scope/upstart
/application-click-com.ubuntu.terminal_terminal_0.5.106
phablet@ubuntu-phablet:~$ apt-cache policy ubuntu-app-launch
