Subtle: dhcpcd.service would call resolvconf during shutdown, which in
turn would start invalidate-nscd.service, causing the shutdown to be
cancelled. Instead, give nscd.service a proper reload action, and do
"systemctl reload --no-block nscd.service". The --no-block is
necessary to prevent that command from waiting until a timeout occurs
(bug in systemd?).
interfaces black-listed for dhcpcd via configuration.nix. I use this option to
disable DHCP for "veth*" interfaces, which are created by LXC for use inside of
virtual machines.

delete routes and addresses when it quits. This causes those routes
and addresses to stick around forever, since dhcpcd won't delete
them when it runs next (even if it acquires a new lease on the same
interface). This is bad; in particular the stale (default) routes
can break networking.
The downside to removing "persistent" is that you should never ever
do "stop dhcpcd" on a remote machine configured by dhcpcd.

yet). It's smaller than dhclient and has more features
(e.g. automatically detects link status changes, supports
openresolv, does IPv4LL, and supports IPv6 Router Advertisements).
