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!

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.
