[SOLVED] Unable to mount EFI system partition after update.

I just updated my system 10 minutes ago, and I attempted to mount my EFI system partition using "sudo mount /dev/sda2 /boot" and it came up with this error: "mount: unknown filesystem type 'vfat'" I know this is a problem, as before this update, I could mount it perfectly fine. Does anyone know the solution to this?

There's no place like 127.0.0.1.

Output of `uname -r && pacman -Q linux`?

Re: [SOLVED] Unable to mount EFI system partition after update.

So you updated without /boot mounted...

I believe systemd mounts and unmounts the EFI automatically, to keep for unexpectedly and accidentally damaging the filesystem (or some such).

Resolved it by making a live USB of Arch on windows and mounting /dev/sda2 before reinstalling the kernel.

If you have that service running...

Sweet.

And it also turns out I didnt even generate a fstab, so thats why it wasnt mounted by default. What fun.
I just went and did now.

systemd mounts it by default, but will now unmount it after a certain amount of time. Mounting in fstab prevents it from unmounting.

Does systemd automount it when it is needed for updating?

It's supposed to. I removed /boot from my fstab when I started testing systemd 220 and removed gummiboot to use bootctl (systemd-boot). It looks like /boot unmounts after 2 minutes, but I've been able to upgrade my kernel and build an initramfs at will.
