Name: vtbd0 > > > === > Mark Millard > marklmi at yahoo.com FYI: boot1.efi works with ZFS. gptboot.efi is basically the one which stripped ZFS-related codes from boot1.efi. And IIUC, boot1.efi shares most codes with loader.efi (except for its own FS module wrapper as a consumer, implemented for UFS and ZFS). It would be deleted in the future (that is your plan, Warner?), but currently still usable. -- Tomoaki AOKI <junchoon@dec.sakura.ne.jp>
