Hmmm... well, complication is in the eye of the beholder. Installing root on ZFS is more work, certainly. Mostly because sysinstall doesn't support it (but the PC-BSD installer does). Once it is set up, it's no more bother than root on UFS during normal use, and personally I'd say a pure ZFS system is simpler and cleaner than a hybrid UFS/ZFS setup[*]. The whole deal with updating gptzfsloader is a thing you only need to worry about on rare occasions; typically only during version upgrades. Unless you're tracking a dev branch or running experimental code. 8.1-RELEASE has v13. 8.2-RELEASE will have v15. 9.0 and 8.3 will probably have v28 -- it's anybodies' guess after that, given Oracle's actions over OpenSolaris. Cheers, Matthew [*] There's a good argument for a system with root on ZFS and data on UFS, as a DB server -- ZFS is not the best performing filesystem for the sort of small randomly located IOs that RDBMSes generate. -- Dr Matthew J Seaman MA, D.Phil. 7 Priory Courtyard Flat 3 PGP: http://www.infracaninophile.co.uk/pgpkey Ramsgate JID: matt...@infracaninophile.co.uk Kent, CT11 9PW
