Doesn't works on latest FxOS

[radare]

In the latest firmware ps reports all apps to be "b2g", there's no different name for them so it cant be identified to be an app. and firewatch reports multiple b2g running error.

The way to get all apps running is "ps |grep ^u" .

You can get the PIDs from there and get the name of the app by reading in /proc/pid/status and grep for ^Name.

Seems like we have to stop to rely on b2g-info and implement the logic from b2g-info in firewatch. Would you provide a starting pull request?

[radare]

Then maybe it's a bug in b2g-info because this is a core command from b2g, and shouldnt report that error.

Btw, b2g-info works fine in my Keon, but fails in the Flame. it would be good for firewatch not to depend on those tools, but those tools should be working fine on the reference device at least..

@lightsofapollo is working on a fix for the Flame.

I tested on 2.0 and it yields Fatal error: B2G main process not found. while 2.2 shows an empty list with This program needs to run as the root user in order to query pids.

I am also looking into using the new memory logs that landed in 2.1: https://bugzilla.mozilla.org/show_bug.cgi?id=1078870 , which give much higher fidelity.

Maybe the problem is related to b2g-info on kitkat based images
