migrate | Convert a Ubuntu install to a ZFS root install

The included migration script will convert a Ubuntu installation of 16.04 or later to a ZFS root installation.

The migration script has been tested on the following distributions:

• Ubuntu 18.04

If you have succefully tested the migration script on a Ubuntu based distribution please make a pull request to update this list.

The installation to migrate must be a UEFI install with the ESP at /root/efi/ESP with a single main / partition with the ext4 fileystem.

Downloading the Script

Because arrowroot is a dependency you must download with submodules:

# git clone --recurse-submodules https://github.com/mrshannon/ubuntu-zroot

Migrating an Install

From a live CD/USB run the migration script:

$ ./migrate sdX

where X is replaced by the drive letter of the drive where the installation to migrate is located.

To get help with additional options use:

# ./migrate -h
