Do these changes allow one to manually set the CRASH_DB_IDENTIFIER? I ask as in bug 1324455 we want to be able to setup CRASH_DB_IDENTIFIER to start with deadbeef for systems under automated testing so that they are not counted in crash counters.

Otherwise this looks okay to me.

ping, why was this still not merged?

Since we error on not being able to read the uuid, how are we going to communicate in a friendly way that people might need to regen their emulator images?

[Dimitri John Ledkov (xnox)]

No, that's not what the logic is.

Check if uuid exist, if not write it out.
Read uuid, return uuid.

Thus if it's non-existant it is created on the fly. Thus there is no regeneration required.

Can you merge trunk?

[Brian Murray (brian-murray)]

Is this useful anymore?
