Upgrading or not to snv_118
The thing about any system that you have put too much data on is the stability of it. While I haven’t seen any major issue with snv_117 and have been fairly happy with it for sometime, OpenSolaris has just been upgraded to snv_118.
For OpenSolaris, upgrading an OS is actually a fairly safe operation… even without any preparation. If you have to upgrade Windows Vista from SP1 to SP2. The only safe way to do it is to take a image dump of the partition with programs like Norton Ghost or Clonezilla and the like. Upgrade the OS and if anything bad happens, rollback to the previous version using the image.
OpenSolaris, if you take advantage of using ZFS as the root filesystem, the update manager actually takes a ZFS snapshot of the OS, then install the new version of the OS on. At boot, you can easily choose to boot to a previous version that was snapshotted (is there such a word)…. no fuss no hassle…
Even with that in mind, it is still a scary thought to upgrade… Let me think about it a bit more…
