Building native apps

[Gábor Paller]

I ran into one more apparmor issue. My apparmor file currently looks like:

{
    "template": "default",
    "policy_vendor": "ubuntu-snappy",
    "policy_version": 1.3,
    "policy_groups": [
        "networking"
    ],
    "read_path": [
"/dev/video0",
"/home/ubuntu/"
   ],
   "write_path": [
"/dev/video0",
"/home/ubuntu/"
   ]
}

I added /home/ubuntu because I want to save output files there, e.g.
/home/ubuntu/1.jpg.

Now I bump the version, install the package but still, the output file
cannot be saved.

root at localhost:~/snappy-bin# ./fswebcam.fswebcam -d /dev/video0 2_2.jpg
...
Error opening file for output: 2_2.jpg

fopen: Permission denied

The thing works perfectly when invoked directly from under the /apps tree.

Regards,
Gabor
