Setuid programs are documented here:

https://www.gnu.org/software/guix/manual/guix.html#Setuid-Programs

Following the "passwd" example, making "X" setuid root would be declared
like this:

(operating-system
  [...]
  (setuid-programs
   (cons #~(string-append #$xorg-server "/bin/X")
         %setuid-programs))

It's not clear to me how to improve this since it's very similar to how
other defaults are overridden. Any suggestions?

TIA!
