I'm not sure if it can boot off GPT disk but on Solaris zpool = automatically creates boundary GPT partition to protect ZFS vdev. Under the Solaris-based OSes I have used*, ZFS creates an = EFI-like disk label, NOT a GPT label. FreeBSD (9.0) will read and use = the EFI-like disk label that ZFS creates (or perhaps it is the ZFS code = that is parsing the disk label). So if you want to move a zpool between = FreeBSD and a Solaris-derived OS, then the safe bet is to give ZFS the = entire disk and let it create the disk label. *Solaris-based OSes that I have used: Solaris 10 OpenSolaris=20 NCP (Nexenta Core Platform) -- Paul Kraus Deputy Technical Director, LoneStarCon 3 Sound Coordinator, Schenectady Light Opera Company
