I'm not sure why it amazes you that people are making widespread use of ZFS. You could make the same argument that people shouldn't use UFS2 journaling on their file systems because bugs in the implementation might make debugging journaled UFS2 file systems "a serious PITA." The point is that there are VERY compelling reasons why people might want to use ZFS for root/var/tmp/usr/etc. (pooled storage; easy snapshots; etc.) and there should come a time when a given file system is "generally regarded as safe." I'd say the time for ZFS came when they removed the big disclaimer from the boot messages. If ZFS is dangerous, they should reinstate the "not ready for production" warning. Until they do, I think it's unfair to castigate people for using ZFS universally. Isn't it a recurring theme on freebsd-current and freebsd-stable that more people need to use features so they can be debugged in realistic environments? If you're telling them, "don't use that because it makes debugging harder," how are they supposed to get debugged and hence improved? :-) Cheers, Paul. _______________________________________________ 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"
