Personally, I find mfsbsd much more practical for booting up a "rescue-environment". Also, if 8.4 does not work for some reason - maybe try 8.3? I have quite a lot of systems running 8.3 (and even more with 9.1) but none of them do zfsroot and none of them stresses ZFS very much. I've so far resisted the urge to update to 8.4. The reason why I would be interested to run zfs-root is that sometimes, you only have two hard drives and still want to do ZFS on it. Ideally, though, FreeBSD would be able to do something like SmartOS (one of the few features I kind of like about it…), where you boot from an USB-image (or ideally, via (i)PXE) but use all the available space for data and (3rd-party) software. That way, you always have something to boot from, but can maximize the usage of spindles and space. A basic FreeBSD install is, I think, less than 0.5G these days - I really hate wasting two 300 (or even 600) GB SAS hard disks just for that. _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
