Set up BTRFS before install, according to this guide
(You are booted in the Arch Live environment meant to install Arch on your machine or VM)
Contents |
Before pacstrap (01:50)
loadkeys for your keyboard
Select device with fdisk -l ; VM devices starts with V here, as in /dev/vda1 et
Partitionning (02:05)
fdisk /dev/vda
- Use g to create a GPT partition table on /dev/vda1
- Use n to create a first EFI partition
- Use +300M to make it 300M in size
- Use t to change its type to 1 to make it an EFI partition
- Use n to create a second partition for the rest of the disk
- Use p to check for values and mistakes
- Use w to write the modifications and exit the interactive fdisk prompt
Formatting (02:50)
- mkfs.fat -F 32 /dev/vda1
- mkfs.btrfs /dev/vda2
Start mounting and playing with BTRFS (04:50)
- mount /dev/vda2 /mnt
- create subvolumes with
btrfs subvolume create /mnt/@ btrfs subvolume create /mnt/@home btrfs subvolume create /mnt/@snapshots
- Check your existing subvolumes and their ID :
btrfs subvolume list /
(Reminder : subvolumes don't create snapshots of nested subvolumes ; here @ won't contain @home or @snapshots data)
- Create mountpoints
mkdir /mnt/efi mkdir /mnt/home mkdir /mnt/.snapshots mkdir /mnt/btrfsroot
- Then Umount the actual /dev/vda2 to replace by the @ subvolume
mount /dev/vda2 -o subvolid=256 /mnt mount /dev/vda2 -o subvolid=257 /mnt/home mount /dev/vda2 -o subvolid=258 /mnt/.snapshots mount /dev/vda2 -o subvolid=5 /mnt/btrfsroot mount /dev/vda1 /mnt/efi
It's pactsrap time now (07:00)
pacstrap -K /mnt base linux base-devel grub sudo git less nano efibootmgr btrfs-progs snapper snap-pac grub-btrfs tar sudo
Sodding network here man...
And now...
* check your mount points list for any misstep with mount
create your fstab file when mount is all ok
genfstab -U /mnt >> /mnt/etc/fstab
Check again with less /mnt/etc/fstab
arch-chroot /mnt if everything is good
- you still have to do the usual : vconsole.conf for the keymap, locale-gen for lang etc, see the arch install guide
- Do the mkinit just in case :
mkinitcpio -P
- Install GRUB with this :
add --removable to the grub install line if necessary then do grub-mkconfig
then reboot
--failed at grub / creating bootable system phase--
