Setuid handling?

[Development of GNU Guix and the GNU System distribution.]

Hi,

After reconfiguring today (see below) I can no longer invoke a
familiar set of setuid executables:

    $ su -
    su: Not setuid and you are not root, expect this to fail
    root's password:

    $ mailq
    mailq: need root privileges

Has the handling for such executables changed?

Kind regards
Felix Lechner
