Proposed netcfg bug merge: DHCP/DNS data overrides preseeded values
I'm grovelling over the BTS for netcfg a bit, and I've noticed that there
are a number of bugs that all cover the same ground: that preseeded values
for get_hostname/get_domain are ignored in favour of values taken from
DHCP/DNS (different bugs mention different sources).
Unless there are any objections, I'll merge the following bugs together into
one bug, 606636 (as it has the most discussion, as well as a patch that
seems like it solves the whole problem).
544513: dhcp returned hostname takes precedence
has patch from 2009 that changes the default behaviour, making
preseeded value for get_hostname take precedence over DHCP
ML discussion indicates this probably isn't acceptable.
343269: hostname/domain name preseeding quite broken
No discussion since initial report
606636: Reverse DNS takes precedence over netcfg/get_hostname
Lengthy discussion with patches for code and docs to add a new
option which is the "highest priority" as a source of FQDN; this
preserves existing behaviour and seems like the best possible
561573: Disable reverse-resolve via preseed
Same problem, no discussion
