Set up BTRFS before install, according to this guide
FAIL Network here is too slow it's infuriating, trying installs is horrible
(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--
