EDIT: it seems that for creating a chroot you still require root.

I don't have root on that system and so I can't create a chroot , there is fakeroot but it doesn't work since it uses qemu on that locked system.

Are there any other alternatives

You actually don't as long as you have user namespaces.

One thing I am working on I use chroot (rather unshare --root=) to minimally sandbox a subprocess. At the beginning of the script I have this little snippet:

    if [ "$(id --user)" -ne 0 ]; then
     exec unshare --map-root-user --mount -- "$0" "$@"
    fi

Though you can probably just do something roughtly as `unshare --map-root-user --root=<PATH>`.

Fakeroot is good for the debootstrap step, and then schroot runs unprivileged.

fakeroot has nothing to do with qemu -- it simply uses LD preload to make commands think they're uid 0
