To be honest, I don't think it's that much of a risk: We get regular power cuts at home (probably 8-10 a year), and I've got a solaris box that was originally snv_70, and is now snv_98 that's survived over half a dozen without any issues at all. It wasn't ZFS boot originally, but has been upgr

Hi, I have a small Linux server PC at home (Intel Core2 Q9300, 4 GB RAM), and I'm seriously considering switching to OpenSolaris (Indiana, 2008.11) in the near future, mainly because of ZFS. The idea is to run the existing CentOS 4.7 system inside a VM and let it NFS mount home directories and ot
