Author: bz Date: Tue May 31 15:02:30 2011 New Revision: 222528 URL: http://svn.freebsd.org/changeset/base/222528 Log: Start teaching pc-sysinstall about IPv6. Add some additional empty string checks for IPv4 and try to configure a netmask along with the address rather than doing things twice. Contrary to AUTO-DHCP, IPv6-SLAAC will accept static configuration as well, which we will use at least for resolv.conf currently and if we were given a static address configure that as an alias as well. The pc-sysinstaller changes going along were committed to PC-BSD as r10773.
