Using chroot
/bin/bash depends of course on libc, ld-linux, libdl etc., you can use ldd /bin/bash to see which libraries it requires.
1) You can mount -o bind these directories under chroot 2) Or you can copy these libraries to chroot, if you don't trust the chrooted env to not corrupt them, like so:
cp main rootfs/ cp -a /usr rootfs/ cp -a /lib rootfs/ cp -a /lib64 rootfs/ chmod rootfs chroot --userspec=test1:test1 ./rootfs /main
