 Unfortunately, the Ubuntu 18.04 image uses a 32-bit kernel, and the available ZFS packages aren't compatible with a 32-bit kernel.  This means I'll need to compile the ZFS pieces myself, and they're not known to be stable with a 32-bit kernel in any event.  Updates to come. Unfortunately, the Ubuntu 18.04 image uses a 32-bit kernel, and the available ZFS packages aren't compatible with a 32-bit kernel.  This means I'll need to compile the ZFS pieces myself, and they're not known to be stable with a 32-bit kernel in any event.  Updates to come.
- +===== Create a non-privileged user with sudo capability =====
-===== Rebuild the kernel ===== +
-In order to build ZFS, you must have the headers for the running kernel installed on the system.  Since there does not appear to be a linux-headers package available matching the kernel version installed on the Odroid, this means you'll need to rebuild the kernel.  To do this, run the following commands (taken from the [[https://wiki.odroid.com/odroid-xu4/software/building_kernel#y|Hardkernel wiki]]):+
 <code> <code>
-sudo apt update && sudo apt upgrade && apt dist-upgrade && apt autoremove +adduser fred 
-sudo apt install git gcc g++ build-essential bc libssl-dev +usermod -aG sudo fred 
-git clone --depth 1 https://github.com/hardkernel/linux -b odroidxu4-4.14.y +</code> 
-cd linux +===== Install the kernel headers ===== 
-make odroidxu4_defconfig +In order to build ZFS, you must have the headers for the running kernel installed on the system. 
-make -j8 +<code> 
-sudo make modules_install +wget http://deb.odroid.in/5422-s/pool/main/l/linux-source-4.14.73-136/linux-headers-4.14.73-136_20181001_armhf.deb

-Then reboot your system to start using the new kernel.
