[Resolvconf-devel] Bug#568821: improved API

Package: resolvconf
Version: 1.45
Severity: wishlist

Looking at /etc/resolvconf/update.d/*, I see a lot of code

  - formatting nameserver lines
  - uniquifying nameserver/search lists

The reason for this is /lib/resolvconf/list-records, which is the
only API resolvconf exposes, and it's rather brittle anyway, since
it has to be run in the right directory.

I suggest that resolvconf grows a new API:

  register-nameservers $NAME [$IP [$IP …]]
    formats the list of IPs and calls resolvconf -a appropriately
    reads list from stdin if ${2…} is empty

  get-nameserver-ips [-a] [$NAME]
    get a list of IPs associated with an interface, or all
    IPs known to resolvconf, properly sorted and uniquified.
    The -a option causes it to override truncating after localhost

  unregister-nameservers $NAME
    calls resolvconf -d for completeness

If there's a strong signal that this is wanted behaviour, I would
write the scripts.
