Not really. The system works fine without it. You just can't dump and if you run out of RAM -- tough. For that matter, you can swap to a file instead of to a dedicated slice. > If we go by the logic of your response, you yourself could easily argue that > the current scheme is useless because there is only /, swap and /export/home, > and no space for live upgrade.

To make LU work well, at least prior to ZFS roots, you'll want to keep system software in a separate slice from add-on stuff. That means a smallish (~8GB) root file system, an identical alternate root (another ~8GB), and the rest for /export-type stuff and mounts within /opt for big items. Otherwise, you'll be forcing LU to copy around your user data and third-party applications between boot environments, and that may not necessarily be what you want. It'll be slow and (obscurely) break things if you have any sparse files. -- James Carlson, Solaris Networking <james.d.carlson at sun.com> Sun Microsystems / 1 Network Drive 71.232W Vox +1 781 442 2084 MS UBUR02-212 / Burlington MA 01803-2757 42.496N Fax +1 781 442 1677
