 I file a RFP bug there?

 so it might be worth looking into it.

 Thanks for the pointer. I think filing an RFP sounds like a good idea if
 we go with VMBuilder after we patched it in a way to support up-to-date
 Debian systems (we'll see if we do that).

 Wheezy then) should upgrade to stable
 > Note that Debian oldstable is supported for a full year after a new
 stable is out. So users should, and will upgrade, sure, but not
 necessarily right now: that's what the transition period is for, and I
 doubt we can force users to go through the upgrade exactly when we want
 it. If we try to force it, I'm afraid that the end-result, for many Debian
 users, would simply be "what?! Tor Browser is broken", which isn't very
 nice UX, even with awesome blog posts explaining them (in English) why
 they should upgrade their OS.

 Good point and I agree with you.

 building our Linux packages

 (and probably longer, as it seems likely that the LTS effort will apply to
 Wheezy too), this wouldn't seem _that_ crazy an option to me.
 > It at least would do the first migration step, away from an unsupported
 Ubuntu release, to using Debian for the build VMs. And in a year, once
 Wheezy is officially deprecated (the LTS effort is mostly focussed on
 server use cases in practice), then we can definitely stop supporting
 Wheezy users, and then we can use Jessie VMs to build Tor Browser.

 Maybe, but note that Ubuntu Precise will be supported almost until end of
 2017 which might cause similar glibc issues if we want to support that
 long-term Ubuntu distro while pondering switching to Jessie.

 Wheezy has glibc 2.13, Precise has 2.15 -- the delta perhaps isn't that
 big => maybe there's no new symbol introduced in 2.13..2.15 that Tor
 Browser builds would pick up? It might be, in the end, that it's only
 about one symbol or two, and then perhaps a thin compatibility layer hack,
 like the bitcoin folks have done, could be an acceptable workaround for a

 Having Lucid as the OS for the guest VM is exactly due to glibc issues we
 encountered in the past (a thing the Tor Messenger people had to learn as
 well). We could check if it is really just one or two symbols but I am not
 so happy about that idea given our numerous Tor Browser parts and the
 already fragile build system.

 the year, but I doubt it'll happen before November.)

 So, sticking to Ubuntu Precise a la #15551 is no option then. The
 deterministic build system does already have enough kludges and I am not
 too eager to add another one in the Bitcoin style. Seems Mike was right
 and we should try to get Gitian working with Debian guest VMs. Exciting.
