Ok. I have my feelings on that topic but they may not be as relevant for ZFS. It may be because I tried to avoid single points of failure on other systems with techniques that don't map to ZFS or Solaris. I believe I can bring up several OS without /usr or /var although they complain they will work. But I'll take your point here. > Depending on the OS versions, you can do manual data migrations > to separate datasets of the root pool, in order to keep some data > common between OE's or to enforce different quotas or compression > rules.
