sudo Segfault

[tsuckow]

I've been using this hack on my raspbian image and ran into a minor issue.
https://github.com/tsuckow/rpi-raspbian-qemu

RUN sudo -u warrior /bin/sh -c 'git clone -b docker https://github.com/ArchiveTeam/warrior-code2.git'
qemu: uncaught target signal 11 (Segmentation fault) - core dumped
Segmentation fault (core dumped)

I think it isn't liking getting executed as another user. Does the emulation need root?
