debian-buster-zfs-root
Installs Debian GNU/Linux 10 Buster to a native ZFS root filesystem using a Debian Live CD. The resulting system is a fully updateable debian system with no quirks or workarounds.
Warning
Due to problems with grub-efi-amd64-signed UEFI secure boot has been disabled until a proper solution is available (SoerenBusse has created a fix which has not been reviewd yet).
Usage
- Boot Debian Live CD
- Login (user:
user, password: live) and become root
- Setup network and export
http_proxy environment variable (if needed)
- Run this script
- User interface: Select disks and RAID level
- User interface: Decide if you want Legacy BIOS or EFI boot (only if your hardware supports EFI)
- Let the installer do the work
- User interface: install grub to all disks participating in the array (only if you're using Legacy BIOS boot)
- User interface: enter root password and select timezone
- Reboot
- Star this repository :)
Fixes included
- Some mountpoints, notably
/var, need to be mounted via fstab as the ZFS mount script runs too late during boot.
- The EFI System Partition (ESP) is a single point of failure on one disk, this is arguably a mis-design in the UEFI specification. This script installs an ESP partition to every RAID disk, accompanied with a corresponding EFI boot menu.
Bugs
grub-install sometimes mysteriously fails for disk numbers >= 4 (grub-install: error: cannot find a GRUB drive for /dev/disk/by-id/...).
