| Using "Ubuntu 18.04 Root on ZFS" Instructions on Debian Buster (Testing Live DVD): | |
| 1) Must add contrib repository and run apt update before installing zfs-initramfs | |
| 2) Must run "modprobe zfs" before creating pool | |
| 3) /etc/netplan/01-netcfg.yaml doesn't exist on Debian | |
| 4) Different apt lists, must add contrib | |
| 5) apt install --yes locales is necessary before configuring locales | |
| 6) nano is already installed by debootstrap | |
| 7) Different package names for kernel so you need "apt install --yes dpkg-dev linux-headers-$(uname -r) linux-image-amd64" . However, "apt install --yes zfs-initramfs" works (the current debian instructions also include zfs-dkms but zfs-initramfs depends on zfs-dkms) | |
| 8) The 5.4 Grub instructions don't apply to Debian. The 5.3 instructions on the Debian guide are correct. | |
| 9) Instead of 8.2, you would just run tasksel on Debian |
