Can DESTDIR be a zpool on a MBR/BSD slice? You can do an install from source to a zfs dataset no matter where it exists as that just shows up as any other mount point, but if you want to be able to boot from it I would suggest making it on a GPT disk. I checked and there is a section on the wiki <https://wiki.freebsd.org/RootOnZFS/ZFSBootSlice>; about installing to MBR, but its flagged as will not boot. By the way the setup I sent was installed by using the live CD, creating the zpool, and zfs datasets, and extracting the data manually. I do updates by building from source and installing to clones of root dataset then change zpools bootfs and reboot. With the new dataset. -- Thanks, Dean E. Weimer http://www.dweimer.net/
