Partition scheme

/dev/<device>1	/boot/efi	EFI System	FAT32	- EFI partition
/dev/<device>2	/	Linux filesystem	LUKS+Ext4	- Root partition

$ gdisk /dev/<device>

Command (? for help): o
This option deletes all partitions and creates a new protective MBR.
Proceed? (Y/N): y

Command (? for help): n
Partition number (1-128, default 1):
First sector (34-2097118, default = 2048) or {+-}size{KMGTP}:
Last sector (2048-2097118, default = 2097118) or {+-}size{KMGTP}: +512M
Current type is 8300 (Linux filesystem)
Hex code or GUID (L to show codes, Enter = 8300): ef00
Changed type of partition to 'EFI system partition'

Format partitions

Format EFI partition:

mkfs.fat -F32 /dev/sda1

Format root partition:

cryptsetup luksFormat /dev/sda2
cryptsetup open /dev/sda2 cryptroot
mkfs.ext4 /dev/mapper/cryptroot

Mount created partitions:

mount /dev/mapper/cryptroot /mnt
mkdir -p /mnt/boot/efi
mount /dev/sda1 /mnt/boot/efi

Create swap file (if needed):

Getting started with swap in RHEL 8 manual:

Amount of RAM in the system	Recommended swap space	Recommended swap space if allowing for hibernation
less than 2 GB	2x amount of RAM	3x the amount of RAM
2 GB - 8 GB	1x amount of RAM	2x the amount of RAM
8 GB - 64 GB	At least 4 GB	1.5x times the amount of RAM
more than 64 GB	At least 4 GB	Hibernation not recommended

Key file for initrd

dd bs=512 count=4 if=/dev/urandom of=private-files/keyfile iflag=fullblock
sudo cryptosetup luksAddKey /dev/sda2 private-files/keyfile

Use store on /mnt

herd start cow-store /mnt

Update channels

TODO: add nonguix channel

guix pull

TODO: set GUIX_PROFILE and load $GUIX_PROFILE/etc/profile

Clone dotfiles repo

guix shell git -- git clone https://github.com/rsauex/dotfiles.git

(TODO)

• lsblk -o ‘NAME,LABEL,RM,RO,SIZE,TYPE,FSTYPE,MOUNTPOINT,UUID’
• non-guix channel
• drives UUID??

(TODO) Install bootstrap system

guix system init -L /root/dotfiles ???.scm /mnt

• install bootstrap home

(TODO) Configure to full system

• pull
