Heh, that doesn't sound like much fun. I have a VM I can experiment with, but I don't want to do this badly enough to take that risk. > There's very little you can safely move in my experience. /export > certainly.

My OpenSolaris installation didn't come with a /usr/local directory. How can mounting a filesystem from a non-root pool under /usr possibly mess anything up? > On my 2010.02/123 system I see: > > bin Symlink to /usr/bin > boot/ > dev/ > devices/ > etc/ > export/ Safe to move, not tied to the 'root' system Good to know. > kernel/ > lib/ > media/ > mnt/ > net/ > opt/ > platform/ > proc/ > rmdisk/ > root/ Could probably move root's homedir I don't think I'd risk it. > rpool/ > sbin/ > system/ > tmp/ > usr/ > var/ > > Other than /export, everything else is considered 'part of the root > system'.

Yeah, that's my fallback. Actually, that along with copies=2 on my root pool, which I might well do anyhow. But you people are making a pretty strong case for making the effort to figure out how to do the mirror thing.
