Kayak Interactive Installer

Starting with r151022, the ISO and USB interactive installers are new. They install on whole-disks, and multiple disks can be selected to make mirrored rpools. Also, blkdev devices (e.g. NVMe, vioblk) can now be detected. Custom rpools can also be built, and the installer can just install the bits on a preconfigured rpool.

BSD Loader Menu

See the Loader usage documentation. The new ISO/USB media for r151022 and later will boot with the Loader instead of GRUB.

Language Selection and Main Menu

Like the old installer, the first thing to come up after boot is the keyboard-layout selector:

And then the installer displays its main menu:

Installer main menu

The first two items are for installing on to a new root pool rpool . The first one goes through disk-selection (see below) followed by an installation, the second assumes rpool was constructed already, and proceeds straight to it. For cases where the rpool is comprised of mirrored slices (for example, to split an SSD pair between slog and rpool), the second entry should be selected.

Before this installer, certain tricks like this needed to be used. Now, one can use the Shell first (option 3) to create a custom rpool as well as anything else, and then use the straight-to-pool (option 2) method for installing on the rpool. The Shell can also be used post-installation (see below).

Disk Selection

Available disks are displayed seven (7) at a time on one screen:

Multiple disks selected will form an N-way mirror. Only a mirror or a single-disk pool can serve as an rpool.

Installation

After rpool creation, the installer will prompt for a few more questions, including time-zone selection. Then it will zfs receive an on-media ZFS send stream to create rpool/ROOT/omnios, the first Boot Environment (BE) on this rpool. It will also create swap and dump datasets on rpool.

Post-install

After installation, the main menu returns. The shell is still available, and the new rpool is mounted on /mnt for further editing. /mnt/.initialboot contains commands that will run exactly once at first-boot time. Network configuration could be done here, for example. Other configuration on /mnt/etc could be done at this time as well via the shell. Once the machine reboots, the newly-installed rpool will display Loader and then boot into the newly-installed BE.
