Hi Roy,

the problem is actually a bit stranger:

on the 1st execution, no daemon created, on the 2nd execution and any subsequent as I described.

  killall dhcpcd
killall: dhcpcd: no process killed
# dhcpcd -t 5 -6 eth0
dhcpcd-9.3.4 starting
DUID 00:01:00:01:0d:2b:80:16:c0:ee:40:c0:17:3d
eth0: IAID 40:51:4e:0e
eth0: soliciting an IPv6 router
eth0: Router Advertisement from fe80::a273:876b:598:9dcf
eth0: no global addresses for default route
timed out
dhcpcd exited
# ps ax | grep dhcpcd
   940 root     grep dhcpcd

# killall dhcpcd
killall: dhcpcd: no process killed
# dhcpcd -t 5 -6 eth0
dhcpcd-9.3.4 starting
DUID 00:01:00:01:0d:2b:80:16:c0:ee:40:c0:17:3d

dhcpcd exited
# ps ax | grep dhcpcd
   988 root     dhcpcd: eth0 [ip4] [ip6]
  1097 root     grep dhcpcd

I can only summarise that something else is starting dhcpcd for you.
I tested this on Alpine and Devuan Linux, NetBSD and FreeBSD - all worked fine, at no point did any other dhcpcd process start.
