I'd say that you should do what is the simplest: either exit with
error, or start provided interfaces independently.

Yes, it works with this script, thanks a lot. But it will require me
to modify my OpenRC script (I am using Gentoo) which could be
overridden at next update.
If I look at the copyright of the OpenRC script, it seems that it is
provided by you, but I couldn't find it in the dhcpcd git tree.
If you don't want to add the “--nomaster” option, would that be
possible to at least modify the script so that it can be provided
options? I was thinking of something like that:

You could also provide a sample configuration file conf.d/dhcpcd:

======
# You may specify options to provide to the dhcpcd service.
# By default, service will start in master mode with quiet option.
#DHCPCD_OPTIONS=-q

# If the dhcpcd service should start for a single interface (no master mode),
# specify the interface name here.
#DHCPCD_IFACE=eth0

I can provide a PR or a git diff if you prefer.
