did you see the libc-alpha discussion?

the current recommended way to override /etc/resolv.conf is using mount
namespace (or chroot), if user namespace is allowed for non-root users
in the kernel then this can be done without root access.

if you can control resolv.conf per process then options can be set too.
(not ideal solution, but may work for you)
