Sorry, I found that I should be running strace using the -o, -f and -ff=20
options:

strace -o /tmp/guix -f -ff /usr/local/bin/guix-daemon \
       --build-users-group=3Dguixbuild

This gave me the following in the parent process log (/tmp/guix.793):

clone(child_stack=3D0, flags=3DCLONE_CHILD_CLEARTID|CLONE_CHILD_SETTID|SIGC=
HLD,=20
child_tidptr=3D0x404c5f28) =3D 797
close(4)                                =3D 0
accept(3, 0xbfff7224, [110])            =3D ? ERESTARTSYS (To be restarted =
if=20
SA_RESTART is set)
=2D-- SIGCHLD {si_signo=3DSIGCHLD, si_code=3DCLD_EXITED, si_pid=3D797, si_u=
id=3D0,=20
si_status=3D0, si_utime=3D51, si_stime=3D524} ---
waitpid(-1, NULL, WNOHANG)              =3D 797

This resembling what I showed before. Meanwhile in the child process log=20
(/tmp/guix.797) the clone call with EINVAL is this one:

clone(child_stack=3D0xbffedfa4, flags=3DCLONE_NEWNS|CLONE_NEWUTS|CLONE_NEWI=
PC|
CLONE_NEWPID|CLONE_NEWNET|SIGCHLD) =3D -1 EINVAL (Invalid argument)

Again, this is using the 4.9.67 kernel.
