[SOLVED] Seperate /boot from ESP

I want to separate the boot from the small EFI partition. If I understand correctly I must.

1.  Boot with Arch install media.
2.  Mount my root partition
3.  Mount my EFI partition
4.  Move initramfs, vmlinuz, grub  (mv /mnt/efi/initramfs* /mnt/efi/vmlinuz* /mnt/efi/grub/ /boot/)
5.  Create /efi directory
6.  Mount my EFI partition to /efi
7.  Enter chroot
8.  change /etc/fstab
9.  Run grub-install --target=x86_64-efi --efi-directory=/efi --bootloader-id=GRUB
10. grub-mkconfig -o /boot/grub/grub.cfg
11. Install linux

Am I correct?

Re: [SOLVED] Seperate /boot from ESP

You can do this directly from the running main system. assuming the last output is your current setup:

  1. Unmount /boot (which is your ESP?)

  2. create the /efi directory

  3. mount nvme0n1p1 to /efi

  4. mv /efi/initramfs* /efi/vmlinuz* /efi/grub/ /boot/

and then do steps 8. to 10. from your list, 11 isn't strictly necessary wouldn't hurt hugely.
