-# Rpooler
-## A ZFS rpool wrapper for the Ubuntu 18.04 Ubiquity Installer
-This is a wrapper that automates the creation of a fully bootable zfs root pool with Ubuntu 18.04 installed.  It was crafted off the step-by-step [HOWTO install Ubuntu 18.04 to a Whole Disk Native ZFS Root Filesystem using Ubiquity GUI installer](https://github.com/zfsonlinux/pkg-zfs/wiki/HOWTO-install-Ubuntu-18.04-to-a-Whole-Disk-Native-ZFS-Root-Filesystem-using-Ubiquity-GUI-installer).  The goals are to further simplfy the installation process and encourage best practices through the guided process.
-
-Instructions:
-1) Boot Ubuntu 18.04 Desktop Live CD
-2) Select "Try Ubuntu"
-3) Open terminal (Ctrl+Alt+t)
-4) `wget https://raw.github.com/ghfields/rpooler/master/rpooler.sh`
-5) `sudo bash rpooler.sh`
-
-
-## What to expect when running script
-```
-Installer script for ZFS whole disk installation using Ubuntu GUI (Ubiquity)
-----------------------------------------------------------------------------
- What do you want to name your pool?  
-rpool
-
-These are the drives on your system:
- 	 /dev/disk/by-id/ata-VBOX_CD-ROM_VB2-01700376
- 	 /dev/disk/by-id/ata-VBOX_HARDDISK_VB9c4c6292-31c83b83
- What vdev layout do you want to use? (hint: tab completion works):  
-/dev/disk/by-id/ata-VBOX_HARDDISK_VB9c4c6292-31c83b83
-
- Which zpool & zfs options do you wish to set at creation?  
--o feature@multi_vdev_crash_dump=disabled -o feature@large_dnode=disabled -o feature@sha512=disabled -o feature@skein=disabled -o feature@edonr=disabled -o ashift=12 -O atime=off -O compression=lz4 -O normalization=formD -O recordsize=1M -O xattr=sa
-
-Zpool would create 'rpool' with the following layout:
-
-	rpool
-	  ata-VBOX_HARDDISK_VB9c4c6292-31c83b83
-
- Does this look correct (y/n): 
-y
-
-The Ubiquity made swapfile will not function and will be removed.
-Based on your system's 3.85 GB of RAM, Ubuntu suggests a swap of 2 GB.
- What size, in GB, should the created swap zvol be? (0 for none):  
-2
-Zvol swap size: 2 GB
- Is this correct (y/n): 
-y
-
-Configuring the Ubiquity Installer
-----------------------------------
- 	 1) Choose any options you wish until you get to the 'Installation Type' screen.
- 	 2) Select 'Erase disk and install Ubuntu' and click 'Continue'.
- 	 3) Change the 'Select drive:' dropdown to '/dev/zd0 - 10.7 GB Unknown' and click 'Install Now'.
- 	 4) A popup summarizes your choices and asks 'Write the changes to disks?'. Click 'Continue'.
- 	 5) At this point continue through the installer normally.
- 	 6) Finally, a message comes up 'Installation Complete'. Click the 'Continue Testing'.
- 	 This install script will continue.
-
-Press any key to launch Ubiquity. These instructions will remain visible in the terminal window.

+## zfsonlinux community documentation for specific distributions.
+
+ubuntu-ubiquity [HOWTO install Ubuntu 18.04 to a Whole Disk Native ZFS Root Filesystem using Ubiquity GUI installer](https://github.com/zfsonlinux/pkg-zfs/wiki/HOWTO-install-Ubuntu-18.04-to-a-Whole-Disk-Native-ZFS-Root-Filesystem-using-Ubiquity-GUI-installer).
+
+## Goals
+- Simplfy the installation process to the point of automation.
+- Upstream and intergrate as is "legally" possible. I wish this script wasn't required.
+- Encourage best practices through the guides practices.
+
+## Supported distributions
+Currently only ubuntu using the ubiquity installer is the only option.
+
+- ubuntu/bionic
+
+TODO
+- arch
+- gentoo
+- debian
+- rhel
+- centos
+- opensuse
+- linuxfromscratch
+
+## Instructions
+1) Boot supported distribtion
+2) run zfs-install.sh
+3) answer any required questions.
+4) Your done.
+
+## Contributions
+Any and all contibutions in any form are encouraged and most welcome.
+
+There doesn't appear to be many people interested in this project, thats cool!
+I would appreciate the time of any other zfs users. 
+
+- What method do you use to "bootstrap" zfs for your use case ?
+- I'm guessing most people are using packer to create custom iso's. is this Correct ?
