It needs /proc/PID/{exe,cwd,fd,maps,environ}:

  
https://git.savannah.gnu.org/cgit/guix.git/tree/nix/scripts/list-runtime-roots.in

That said, it’s quite optional: the worst that can happen if one of
these things is missing is that something can be reclaimed “prematurely”
from /gnu/store.  I say “prematurely” with quotes because users are
supposed to register “real” GC roots anyway, as with ‘guix package -i’
or ‘guix build --root’.

Thanks,
Ludo’.
