For !EFI, this is relatively easy. boot1 you can type /boot/loader_forth instead of the default /boot/loader if the symlink changes and you want to go back. For EFI the answer is more complicated. boot1.efi is going away, so loader.efi will move to the ESP in \efi\freebsd\loader.efi, but it's easy enough to have multiple versions there (loader_lua.efi and loader_forth.efi) and select via EFI Shell or EFI Env variables which one you want should you need to fall back. Does that answer your concerns? Warner
