Limitations for the OpenSolaris 2008.11 Release

The OpenSolaris 2008.11 release, has the following limitations:

• At this time, the OpenSolaris 2008.11 release is for 32-bit or 64-bit x86 platforms only. This release is not yet available for SPARC platforms.

• The installer cannot upgrade an existing operating system. The installer can perform an initial installation into a Solaris partition or use an entire disk.

  The installation overwrites all the software and data on the selected target. However, you can upgrade all installed packages on your installed system by using the Image Packaging System. See Upgrading An Image.

• The entire content of a preexisting Solaris partition is overwritten during the installation. Existing file systems cannot be preserved.

• The OpenSolaris OS installs a ZFS root file system, not a UFS root file system, on the disk selected during installation. The ZFS pool installed initially consists of the entire Solaris fdisk partition on the selected disk. After the initial installation is complete, you can add additional disks to this pool to create a mirrored pool configuration. For further information, see ZFS Documentation.

• A maximum of 2Tbytes on a disk or on a partition is usable for installing the OpenSolaris 2008.11 release, even if the disk or partition is larger than 2 Tbytes.
