Thanks for the reply.
I thought that "set root=(lvm/fedora/root)" told the boot process where
root was. Where is this stuff documented ?
So I should add something like "root=/dev/mapper/fedora-root" to the
Linuxefi line ? Do I need anything else to get a minimal system running ?

You're missing all the parameters to the kernel that tell it where the
root is.
How do I get my server to boot again ?

That's the wrong place for an EFI system. You need to mount the EFI
partition (probably /dev/sda1 in your case) at /boot/efi and the grub.cfg
is in /boot/efi/EFI/fedora/.
