[SOLVED] Should I mount ESP at boot (UEFI, GRUB, kernels in /boot)

Hello, I’m wondering if I need to leave the /efi entry generated by genfstab in my fstab to mount it at boot. I ask that because I needed to reinstall W10 beside Arch and I accidentally recreated the ESP (which UUID changed), so then I commented out its line in my fstab to be able to boot, and it booted apparently without problems (it seems that I have an error message at boot but it disappears so quick that I cannot read it).

In my ESP, there’s just the grub directory that seems related to Arch (others are boot and microsoft, I don’t know what’s boot but it seemed to be here before grub), others boot things are in /boot, in the same partition than /.

Thanks for your replies !

PS : I’m not english, please excuse me for eventual mistakes.

GRUB will read the kernels from /boot from your root partition. The only time you actively need the ESP mounted if you actively want to update the GRUB binary with the relevant GRUB install command, for everything else it is irrelevant.
