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

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

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

clone(child_stack=0, flags=CLONE_CHILD_CLEARTID|CLONE_CHILD_SETTID|SIGCHLD, 
child_tidptr=0x404c5f28) = 797
close(4)                                = 0
accept(3, 0xbfff7224, [110])            = ? ERESTARTSYS (To be restarted if 
SA_RESTART is set)
--- SIGCHLD {si_signo=SIGCHLD, si_code=CLD_EXITED, si_pid=797, si_uid=0, 
si_status=0, si_utime=51, si_stime=524} ---
waitpid(-1, NULL, WNOHANG)              = 797

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

clone(child_stack=0xbffedfa4, flags=CLONE_NEWNS|CLONE_NEWUTS|CLONE_NEWIPC|
CLONE_NEWPID|CLONE_NEWNET|SIGCHLD) = -1 EINVAL (Invalid argument)

Again, this is using the 4.9.67 kernel.
