An updated pyparted package that fixes a bug is now available for Red Hat Enterprise Linux 6.
The pyparted package contains Python bindings for the libparted library. It is primarily used by the Red Hat Enterprise Linux installation software.
Due to a missing flag in the GPT (Guid Partition Table) disklabel, the anaconda installer terminated with a traceback during the installation of Red Hat Enterprise Linux 6.2. With this update, support for the PARTITION_LEGACY_BOOT flag has been added to the pyparted package, thus fixing this bug.
Users of pyparted are advised to upgrade to this updated package, which fixes this bug.
