Re: Does OpenZFS support taking snapshots of the entire operating system?

You can snapshot a running root filesystem if it is ZFS; that has always 
been true of ZFS.

If the "entire operating system" spans more than one filesystem or pool, 
however, you cannot get an atomic snapshot across them. Thus if you want 
that capacity (e.g. an atomic snapshot that is an "instant in time") the 
"entire operating system" must be contained in one ZFS filesystem.
