[Resolvconf-devel] Bug#425444: libc/resolv.conf upgrade should not crop nameserver list after 127.0.0.1

[martin f krafft]

Package: resolvconf
Version: 1.37
Severity: normal
Tags: patch

If a machine has a local recursor, it makes sense to have 127.0.0.1
as the very first nameserver listed in resolv.conf.

resolvconf's libc upgrade script uses a function
uniquify_nameserver_list(), which says:

  # Returns NSMSRVS -- space-separate list of no more than 3 items,
  #                    without duplicates, truncated after 127.*

while interface-order(5) says

  # /etc/resolvconf/interface-order
  # Use nameservers on the loopback interface first.
  lo*
  [...]

These two disagree and in fact, if lo and eth0 both define
dns-nameservers in /e/n/i, then the libc upgrade script will *only*
put the 127.0.0.1 entry into resolv.conf because it truncates the
uniquified nameserver list after encounter of 127.*.

I simply deleted the check for 127.* in the uniquify_nameserver_list
function and it works fine. Why do you crop after 127.*?
