That=E2=80=99s not perfect= , but it=E2=80=99s a rather easy addition. Another option would be to have built-in support in the daemon. If you turn on some option, it would transparently run derivation builds in qemu-user (does that support changing the system date?) or similar, but that=E2=80=99s more work. Ludo=E2=80=99.
