You can't install OpenSolaris into a logical / extended partition. For OpenSolaris a primary fdisk partition must be used. OpenSolaris doesn't allow access to extended partitions[*], with the exception of limited support in mount_pcfs. [*] but I think that'll change; a few weeks ago some bits for improved extended partition support have been integrated into the core OS and should appear in build 119. http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=6644364 OpenSolaris shouldn't access the linux swap, anyway. So it doesn't matter for OpenSolaris that linux swap is inside an extended partition; that way it is hidden from OpenSolaris (Hmm, it is hidden until the above mentioned improved extended partition support is there, I guess...). > Ubuntu originally installed itself inside > and extended partition and I did some partition > juggling copying the partition off and back again > using and external hard drive so that the drive did > not contain any extended partitions.

OTOH, the problem with Linux and (old) Solaris using the same fdisk partition id exists for Linux swap slices only. -- This message posted from opensolaris.org
