[arch-general] problems on installing grub on a new system

[Steve Downes]

Can someone point me at what I've missed please:-

I'm doing a new installation of archlinux & got as far as installing
grub apparently without problem. Installing grub gives:-

Failed to get canonical path of `airootfs'

This means nothing to me & I can't find anything. Could use some
guidance before I start again, or even better instead of starting
again.
