My zfs only system works fine but it based on 8-beta2 built around 16 May( will be rebuilding soon) The main thing to remember to do it make sure your have zfs_loader_support="yes" in your src of make.conf I based my install on this howto http://wiki.freebsd.org/ZFSOnRootWithZFSboot#installFreeBSD If you dont want to go for current in theory if you install the boot blocks and loader from current onto the disk you should be able to boot into 7.2 I havent tested this though On thing I would advise though is don't install the root partition in the root of the zpool I have mine like this system 68.1G 74.6G 21K /system system/home 59.3G 74.6G 59.3G /home system/local-old 952M 74.6G 952M /system/local-old system/root 4G 77.1G 1.53G legacy system/scripts 20K 74.6G 20K /usr/local/scripts system/tmp 31K 4.00G 31K /tmp system/usr-local 396M 74.6G 324M /usr/local system/usr-obj 1.85G 74.6G 1.65G /usr/obj system/usr-ports 193M 74.6G 185M /usr/ports system/usr-ports/distfiles 8.53M 74.6G 8.53M /usr/ports/distfiles system/usr-src 499M 74.6G 303M /usr/src system/var 1014M 74.6G 776M /var system/var/log 192M 74.6G 192M /var/log system/var/mysql 46.4M 74.6G 46.4M /var/db/mysql I did it like this as it is more like an opensolaris setup. If i wanted to say run a new os build I could say install it on a new zfs fs called say root_YYYYMMDD which would be a clone of the original root. I could then flip flop between these installations by resetinng the bootfs option of the pool
