https://groups.google.com/forum/#!topic/mozilla.dev.fxos/FoAwifahNPY announced that the Boot 2 Gecko (B2G) code will be removed from mozilla-central. This is the tracking bug for that.

Once all this code has been removed, will there be components in Bugzilla which are not in the B2G product which should be closed out and moved to Graveyard?

Cloud Services::MobileId (service which provided authentification by phone number as alternative to Firefox Accounts, no idea if it is still running and MoCo is bound by contracts to keep the status like this) Core::DOM: Apps (bug 1291291) If the Gonk widget gets removed: Core::Widget: Gonk Developer Documentation::Firefox OS (I assume with B2G product you mean "Firefox OS" and that this product will be graveyarded on BMO). mozilla.org::Security Assurance: Firefox OS Tech Evangelism:Preinstalled B2G Apps Websites::Master Firefox OS Websites::mobilepartners.mozilla.org (unsure if it was also used for Android or iOS, but that site redirects to mozilla.org)

Is the battery and reset related stuff also going to be removed ? I'm currently doing some cleanups / trimdowns on esr52 and already collected some nukeb2g patches

Anyone interested in patches against the esr52 branch ?

What about fixes for build switches ? If you were a build peer, you could probably (somewhat ironically) make the argument that build switch cleanup is not part of the build, and therefore land it on ESR. But, in practice, you won't actually find a build peer who's willing to make that argument and greenlight landing those patches on ESR for you.

What exactly is a build peer ?

Can I find the source code of dependent bugs on Github? Where I can PR the code.

This bug is only about the backend code which was part of mozilla-central. The frontend code was in a separate repo - "gaia". So patches have to be for mozilla-central. Not every dependent bug will have checked if all the called code in the code which got removed is still needed. A static analysis could detect those. If you want to manually find something to work on, search the source code for "B2G" or "Mulet".
