I didn't say _/etc/resolvconf_ (which is a directory).
I said _/etc/resolv.conf_ (which is a regular file).

/etc/resolv.conf is an ancient, primordial Unix feature, from the
earliest days of TCP/IP, probably invented about a day or so after
someone thought of the concept of DNS.

/etc/resolvconf is a directory containing configuration files for a
network-management framework called Resolvconf, so called because it's a
set of tools for managing the contents of the /etc/resolv.conf file.
(The naming of Resolvconf is at best unfortunate, as the namespace
collision causes all sorts of problems.)

Anyway, pretty much every TCP/IP-enabled Unix host has always had
/etc/resolv.conf, along with /etc/hosts and /etc/nsswitch.conf.
Those three IIRC are the configuration files for the built-in system DNS
resolver facility built into glibc.
