Hi Eric, > The "Solaris Root" partition type is relevant to UFS, not ZFS. On UEFI, set s0/p1 to be an ESP, "boot, hidden, esp" flags and format it fat32
Yep, I have done that quite a while ago. Linux is booting alright with that. > your "Solaris Reserved" should be s8/p9, 8Mib, -1MiB from end of disk . That's for legacy / MBR partitions. Mine is GPT. I don't need that or any other partition for Solaris. I only need one single partition of zfs / illumos and that's working so far. > /EFI/OpenIndiana/bootx64.efi (copy of loader.efi) I put mine on /EFI/Solaris/ I might try rEFInd in future. Right now, I'm booting everything using Linux's bootloader.
