This problem affects systems running the Solaris 2.5.1 and the Solaris 2.5.1 unbundled CDE operating environments. However, these systems are only affected if the unbundled CDE has been relocated to a directory other than /usr/dt. The CDE relocation on these systems has been accomplished by creating a symbolic link in /usr/dt that points to the relocated CDE.
When you upgrade to the Solaris 8 operating environment, CDE is also reinstalled in /usr/dt, and the link to the relocated version is removed. The relocated CDE itself is not removed and is therefore orphaned.
If the upgrade involves the reallocation of file systems, the upgrade may fail because the reallocation mechanism does not account for the extra space needed in /usr/dt for the new version of CDE. This failure is not visible until the upgrade has been completed. If this failure occurs, the upgrade log will include a number of messages indicating that more space is needed for an upgrade.
Workaround: Uninstall the relocated CDE before you start upgrading to the Solaris 8 operating environment. This can be accomplished by using the install-cde script from the Solaris 2.5.1 CDE CD. This script should be run with the -uninstall flag to remove CDE.
