I moved my EFI partition which caused me to enter emergency mode on reboot.

`mount -a` confirmed fstab had the the UUID of the old partition...it wasn't mounting and that caused emergency mode.

You can't do ANY of the standard remount,rw tricks that normally work... it will always give you an error message the mount doesn't work

Sure, I could start from the USB stick and edit /etc/fstab, but isn't there an easier way?
