The most appropriate (supportable by Oracle) is to use the automated installer. An example of the manifest is: http://dlc.sun.com/osol/docs/content/dev/AIinstall/customai.html#ievtoc > The caiman installer allows you to control the size of the partition on the > boot disk but it doesn't allow you (at least I couldn't figure out how) to > control the size of the slices.

There are perhaps a half dozen ways to do this. As others have mentioned, using fdisk partitions can be done and is particularly easy when using the text-based installer. However, with that option you need a smarter partition editor than fdisk (eg. gparted) And, of course, you can fake out the installer altogether... or even change the source code... -- richard ZFS storage and performance consulting at http://www.RichardElling.com ZFS training on deduplication, NexentaStor, and NAS performance Las Vegas, April 29-30, 2010 http://nexenta-vegas.eventbrite.com _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
