so that we're more useful in multi-user mode. This is still not 100%, but it pulls in a lot more than it used to. Some of the "composite" variables in /etc/sysconfig are going to take more work. o Always write /etc/resolv.conf and /etc/hosts if it makes sense to do so. o Reset media properly when reselecting. Longstanding bogon. o Pull SIGPIPE handling out of package.c; I'm actually hoping to handle this differently shortly. o Fix bug where cancel in TCP setup dialog still checked data fields. I think this closes a PR, but I will have to go look.
