Ugh, I forgot a step you might need. Due to the patching, /usr/src/sys/cddl/compat/opensolaris/sys/acl.h and /usr/src/sys/cddl/compat/opensolaris/sys/callb.h become empty and if they exist, should be deleted before compiling because they will cause the compile to fail.

Its reported to fix a number of problems, and add new features. The patch does not apply to 7, that won't be available for a while apparently, but they are looking for feedback on the fs or current mailing lists to encourage sooner integration (possibly by 7.1). Quick instructions: fetch http://people.freebsd.org/~pjd/patches/zfs_20080727.patch.bz2 bunzip2 zfs_20080727.patch.bz2 cd /usr/src/ patch -p0 < /path/to/zfs_20080727.patch do a FULL upgrade of world/kernel. kmem tweaks may still be needed but its a little more resilient than before, also 8-current now lets you configure a larger kmem than the previous ~1.8G limit. It is recommended to remove other tweaks from loader.conf such as zil_disable, etc and see how it does. I've upgraded my laptop and so far so good, but I don't have dovecot on any systems with ZFS so I can't test that aspect.
