It is created automatically on GPT and it is used to store fabricated disk identifier for case the disk does not provide one for itself. It is originating from Solaris and since illumos is fork of Solaris, it is still there. MBR+VTOC setup is using space from ‘alternates’ for the same purpose. rgds, toomas > > > /EFI/OpenIndiana/bootx64.efi (copy of loader.efi) > I put mine on /EFI/Solaris/ > > I might try rEFInd in future.
