My primary system at home is setup this way - primarily because at the time I built it (Nov 2008), I felt ZFS was a bit immature and wanted to have src and obj on UFS so I could do a rebuild if I lost access to ZFS for some reason. My experience has been that the UFS root has caused me far more headaches than the ZFS parts. I've since done some reconfiguration and plan to switch to ZFS root soon. Based on my experiences at home, I converted my desktop at work to pure ZFS. The only issues I've run into have been programs that extensively use mmap(2) - which is a known issue with ZFS. --=20 Peter Jeremy --J/dobhs11T7y2rNN Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.15 (FreeBSD) iEYEARECAAYFAk0eaFcACgkQ/opHv/APuIfZVACghX22o9VApA1p7JXQjp9wo2hV FRQAnA8MIfY2HaPawlVqdpeXb3ebTcYw =+olt -----END PGP SIGNATURE----- --J/dobhs11T7y2rNN--
