Its not so bad: this machine is doing backups with rsync, sometimes running 50 simultaneously. This workload doesn't contain any need for synchronous operations, and any files which didn't get written after a crash can simply be re-rsync. But I hope eventually it will be fixed! > I'm talking about the most commonly-encountered problem: kmem > exhaustion. People want to be able to install FreeBSD then say "Okay! > Time to give ZFS a try!" on some separate disks, and have it work. Personally I don't think there's much point worrying about how to boot off ZFS at this stage until the code is up to date, stable, and running 7-STABLE branch. Until then I will also prefer to have a UFS root volume and just run ZFS for /usr and /home, because I still don't completely trust ZFS and I have a high value on being able to boot the system and have my tools available in /bin and /sbin. - Andrew
