This is with dhcpcd-9.0.2-60-gdad38acf, built without privsep, running
under systemd on Linux.

My config is:

    noipv4ll
    noipv6rs
    nohook resolv.conf
    allowinterfaces enp1s0
    interface enp1s0
        waitip 4
        release
        # noipv6
        ipv6rs
        ia_pd 1 enp2s0/1 enp3s0/2 wlx00c0ca974683/3

If I apply this patch to the 20-resolv.conf hook:

    +		add_resolv_conf
    +	elif $if_down; then
    +		remove_resolv_conf
    +	fi
    +	;;
    +esac

I get this in my logs:

    May 21 23:53:35 gateway dhcpcd[1370]: reason: PREINIT
    May 21 23:53:35 gateway dhcpcd[1370]: skip_hooks:

    May 21 23:53:35 gateway dhcpcd[1370]: reason: PREINIT
    May 21 23:53:35 gateway dhcpcd[1370]: skip_hooks:

If I move the `nohook resolv.conf` line under the interface definition
in my config file I get the same result.

Let me know if there is some more information I can provide :-)
