Does initgroups need access to /etc/group? How does this combine w/
-chroot?

Added bonus...this will fail when the initial user is not privileged
_and_ is the same user as -runas user (probably not what a user intended,
but would've worked before). Something like:

[doh@laptop qemu]$ qemu -runas doh
