Symlinks do not work on FAT file systems, so I assume you mean a symlink placed in /boot (assuming that is UFS or ZFS), which points to /boot/efi/efi/freebsd? At the moment I think installworld would not write 'through' such a symlink. In fact, it makes a hard link from /boot/loader_lua.efi to /boot/loader.efi, unlinking any previous /boot/loader.efi. That said, it would be nice to have some sort of semi-official way of upgrading the real EFI loader through installworld. It would probably require some top-level Makefile magic. -Dimitryhelp
