I missed the start of this thread, but I just wanted to mention that Emacs cannot build inside a docker container at the moment because of the personality syscall.

See https://debbugs.gnu.org/cgi/bugreport.cgi?bug=23529

The result of the "portable dumper" thread is likely to yield a solution to this problem (wether we end up using a portable dumper or not).
