description |
When prompted for a hostname during installation, on my network the default offered is always our second NTP server's IPv6 address, which it received via stateless DHCPv6. netcfg seems to be using the wrong field as a hostname, in the absence of an explicit DHCP-provided hostname.

...and then the installer prompts me for a hostname with a pre-filled default of "2001:630:212:200::123:1b". |
[Impact]
IPv6 autoconfiguration installs badly records NTP server name.
[Test case]
Install Ubuntu (using d-i), in an IPv6 network. The DHCP server should provide NTP servers, but no hostname.
Verify that the default offered for the hostname during install is a correct value, and is not the hostname of the NTP server provided from DHCP.
[Regression Potential]
If any existing location depends on this bad behavior, it would obviously regress. Also to consider are cases where there might be an incorrect recording of the NTP servers or DNS nameservers, DNS search list given the changed code path in this section of the netcfg code.
Any incorrect parsing of a DHCPv6 response while autoconfiguring a system during installation would be a possible regression for this SRU.
