	Trying to install 9.0-RC1 amd64

>Description:

I tried to install a machine for use with src/tools/sysbuild, and ran
into a number of weird issues.

Here is a blow by blow account:

	ada0 zeroed before boot
	boot dvd
	Choose "Install"

	Keymap Selection -> No
		"non-default key mapping" ???
		What kind of question is that ?

	Guided disk
		Hmm, maybe I should use the manual option,
		lets see, where is the "back" button ?
		Ohh, there are *no* "back" buttons *anywhere* ?

	Partition
	ada0 Modify
		"Invalid argument. arg0 'ada0'
	MBR

	Create
	10GB

	Create
	10GB

	Create
	10GB

	Create
	default size

		Active partition is the last one created ?
		There is no place I can see it ?
		There is no place I can change it ?

	ada0s1 Modify
		"Invalid argument. arg0 'ada0s1'
	BSD
	Create (ada0s1a)
	freebsd, full size, /

	Finish

	Enter shell in new system

	gpart set -a active -i 1 ada0
		Fix the active partition

	sysctl kern.geom.debugflags=16
	gmirror label root ada0

	Fix /etc/fstab ?
		There is no /etc/fstab ?
		Create /etc/fstab: /dev/mirror/roots1a / ufs rw 1 1
	boot0cfg -B /dev/ada0

	reboot

	Comes up
		/etc/fstab now contains ada0s1a ?

	fix /etc/fstab
	add geom_mirror_load="YES" to /boot/loader.conf
	reboot

	Comes up


>How-To-Repeat:
	Per above.

	I tried once before with a disk which contained a Ubuntu installation,
	there I ended up with partition 2 having size of "-37GB" on a 40GB
	drive.

>Fix:

	At the very least, show people what's going on.
	And for goodness sake, add "Back" buttons, OK ?

	You really don't want me to write sysinstall2, right ?  :-)
