Comment 4 for bug 1815869

With some more investigation I would summarize that using privileged containers is unsupported in snapd.

ubuntu@xenial:~$ sudo snap install core --beta
error: cannot perform the following tasks:
- Setup snap "core" (6405) security profiles (cannot setup udev for snap "core": cannot reload udev rules: exit status 2
udev output:
)
- Setup snap "core" (6405) security profiles (cannot reload udev rules: exit status 2
udev output:
)

I will resort to fixing the file inheritance issue for now.
