Yes, in a separate terminal as
NIX_SUBSTITUTERS="" guix-daemon --build-users-group=nixbld

-rw------- 1 root root 0 Dez 10 23:30 30001
/etc/group contains a line
nixbld:!:30000:nixbld1,nixbld2,nixbld3,nixbld4,nixbld5,nixbld6,nixbld7,nixbld8,nixbld9,nixbld10
and /etc/passwd:
nixbld1:x:30001:65534:Nix build user 1:/var/empty:/noshell
...
nixbld10:x:30001:65534:Nix build user 10:/var/empty:/noshell

strace ./pre-inst-env guix-build hello 2>&1 | grep fcntl | grep F_SETLKW
returns nothing.
