Thanks Andrei,
I tried various directories but all error:

address@hidden baz]# grub2-install --efi-directory=/tmp
Installing for x86_64-efi platform.
grub2-install: error: failed to get canonical path of `tmpfs'.

address@hidden baz]# grub2-install --efi-directory=/dev/null
Installing for x86_64-efi platform.
grub2-install: error: failed to get canonical path of `devtmpfs'.

address@hidden baz]# grub2-install --efi-directory=/home/baz
Installing for x86_64-efi platform.
grub2-install: error: /home/baz doesn't look like an EFI partition.

Any ideas?

Yes that works fine

I will post to -dev ML.
