Did anybody happen to see this recent flag day message on OpenSolaris?
Solaris now understands Logical Drives in Extended Partitions. That means, Solaris can now be installed in extended partitions and it can also mount them.
Most of the systems comes pre-installed with Windows leaving only extended partitions for multiboot. Linux supported extended partition for a long time. This feature should have been in Solaris by the time the OpenSolaris distro was released. Well, better late than never..
