I guess if I had to start with ifupdown anew, then perhaps yes I'd be a
bit overwhelmed by all the bells and whistles. I have been using it
pretty much from the beginning and I just skip the bits I don't need.

Can dhcpcd also execute "arbitrary" commands when bringing up and taking
down interfaces? I recently had a need to spoof a MAC address for my
wireless interface, for example, and I like to hang interface specific
iptables/nftables rules onto my interfaces when/if they're up.

Hope this helps,
