I decided to try ZFS-FUSE is my ongoing attempt to employ filesystem snapshots in my servers. ZFS-FUSE is in beta but I thought I would give it a try and see what happened. The install was not too difficult other than having to install a bunch of library dependencies along the way. These steps may work on other versions of Ubuntu, Debian, or other Debian derived distros but they have only been testing on Ubuntu 8.04.
