	install kernel ftp enables epsv4 by default, which causes problems with
	some firewalls.
	Attempt to do an FTP install from behind a firewall which does not
	allow incoming connections to your address. Note that when FTP enters
	Extended Passive Mode, it is dead in the water after that.
	exit sysinst and clean up /mnt mounts
	cat >>.netrc
	macdef init
	epsv4 off

	^D	(preceded by a blank line)
	re-run sysinst and find that it works now.
