Scripting and logging functionality for sysinst. Child programs are run in a "display window" so you can actually see what they did before the screen flashes back and you loose it all. Lots of curses fixups. Removed nasty endwins that mangled the tty upon rentry. Change the yes/no box to accept Y or N, and not require cursor motion to decide one or the other. Perform curses redraws when doing things that could cause the kernel to spew printfs onto your screen.
