==== '''Simple nixos zfs installation''' ==== | |||
Start from here in the NixOS manual: [https://nixos.org/manual/nixos/stable/#sec-installation-manual]. | |||
Under manual partitioning [https://nixos.org/manual/nixos/stable/#sec-installation-manual-partitioning] do this instead: | |||
'''Partition your disk with an boot and an zfs partition with your favorite partition tool.''' | |||
Eg. 1G for boot partion, rest for zfs. | |||
Example output from fdisk: | |||
<syntaxhighlight lang="bash"> | |||
fdisk /dev/nvme0n1 | |||
Command (m for help): p | |||
Disk /dev/nvme0n1: 931.51 GiB, 1000204886016 bytes, 1953525168 sectors | |||
... | |||
Device Start End Sectors Size Type | |||
/dev/nvme0n1p1 2048 2099199 2097152 1G EFI System | |||
/dev/nvme0n1p2 2099200 1953523711 1951424512 930.5G Linux filesystem | |||
</syntaxhighlight> | |||
'''Note:''' Remember to set boot partition (first partition) to "EFI System" type | |||
'''Make zfs pool with encryption and mount points:''' | |||
<syntaxhighlight lang="bash"> | |||
zpool create -O encryption=on -O keyformat=passphrase -O keylocation=prompt -O compression=on -O mountpoint=none -O xattr=sa -O acltype=posixacl zpool /dev/nvme0n1p2 | |||
zfs create -o mountpoint=legacy zpool/root | |||
zfs create -o mountpoint=legacy zpool/nix | |||
zfs create -o mountpoint=legacy zpool/var | |||
zfs create -o mountpoint=legacy zpool/home | |||
mkdir /mnt/root | |||
mount -F zfs zpool/root /mnt | |||
mkdir /mnt/nix /mnt/var /mnt/home | |||
mount -F zfs zpool/nix /mnt/nix | |||
mount -F zfs zpool/var /mnt/var | |||
mount -F zfs zpool/zpool /mnt/zpool | |||
</syntaxhighlight> | |||

'''Make fat filesystem on boot partition''' | |||
<syntaxhighlight lang="bash"> | |||
mkfs.fat -F 32 -n boot /dev/nvme0n1p1 | |||

'''Installation:''' | |||
Install: [https://nixos.org/manual/nixos/stable/#sec-installation-manual-installing] | |||
Jump to "2. UEFI systems" | |||
<syntaxhighlight lang="bash"> | |||
mkdir -p /mnt/boot | |||
mount /dev/disk/by-label/boot /mnt/boot | |||
</syntaxhighlight> | |||
Jump to "4." ... /mnt/etc/nixos/configuration.nix ... | |||
Continue from here and add this Boot loader config to your configuration.nix: | |||
<syntaxhighlight lang="nix"> | |||
Boot loader config for configuration.nix: | |||
boot.loader.grub = { | |||
enable = true; | |||
zfsSupport = true; | |||

mirroredBoots = [ | |||
{ devices = [ "nodev"]; path = "/boot"; } | |||

}; | |||
</syntaxhighlight> | |||
