[Bug 1892798] Re: systemd package missing resolvconf(8) compatibility symlink, and a Provides: resolvconf

[Jason A. Donenfeld]

By the way, Arch manages the possibility of openresolv colliding with
systemd's resolvconf by providing a package called "systemd-resolvconf":
https://www.archlinux.org/packages/core/x86_64/systemd-resolvconf/
https://github.com/archlinux/svntogit-
packages/blob/packages/systemd/trunk/PKGBUILD#L239-L251

This seems like a perfectly reasonable way to accomplish this. Simply
package the symlink in a separate package, and then the "Recommends:"
for wireguard just includes systemd-resolvconf in the list alongside
openresolv and resolvconf.

That seems like an exceedingly reasonable way of going about things. Why
not just do the same thing here?

Title:
  systemd package missing resolvconf(8) compatibility symlink, and a
  Provides: resolvconf

Status in systemd package in Ubuntu:
  Won't Fix
Status in wireguard package in Ubuntu:
  Confirmed

Bug description:
  By default Ubuntu now uses systemd to manage the nameservers in
  resolv.conf, so resolvconf and openresolv seem to be redundant.
  However, it appears that systemd's resolvectl is compatable with
  resolvconf style commands if symlinked as resolvconf.

  I'm not really sure how deb packaging works, but if it possible to
  check for the resolvconf command, and if not found just symlink
  /usr/bin/resolvectl to /usr/sbin/resolvconf then wg-quick will work
  without additional packages.

  See
  https://manpages.ubuntu.com/manpages/focal/man1/resolvectl.1#compatibility%20with%20resolvconf(8)
  for more info.

  Apologies if there is a better place to direct this info.
