dhcpcd-discuss

Hi Roy,

Not sure if this is primarily an issue with dhcpcd or openresolv, or both.

According to the "resolv.conf" man page, for example here:

  http://linux.die.net/man/5/resolv.conf

  The domain and search keywords are mutually exclusive.
  If more than one instance of these keywords is present,
  the last instance wins.

When dhcpcd is configured with:

  option domain_name, domain_search

I.e., specifying both in order to handle all kinds of DHCP servers, not 
knowing which of the two options the server can provide, dhcpcd 
generates a "resolv.conf" file that contains both keywords.

The openresolv scripts fail to normalize these mutually exclusive 
keywords, generating a combined file that still contains both.

The Debian resolvconf script, or rather its libc subscriber, normalizes 
multiple occurrences of domain and search lines from different 
publishers into a single search line. This produces a valid 
"resolv.conf" file with only the search keyword, but including all the 
information from all the domain and search lines in the various 
individual "resolv.conf" files.

Thanks,

Joachim
