RHBA-2013:0476 - yaboot bug fix and enhancement update

Synopsis

yaboot bug fix and enhancement update

Type/Severity

Bug Fix Advisory

Topic

Updated yaboot packages that fix one bug and add one enhancement are now available for Red Hat Enterprise Linux 6.

Description

The yaboot packages provide a boot loader for Open Firmware based PowerPC systems. Yaboot can be used to boot IBM eServer System p machines.

This update fixes the following bug:

  • Prior to this update, the yaboot loader used by default a maximum block size of 512 bytes in the fdisk partition table. As a consequence, yaboot could not load a kernel in a disk that was formatted using 4 kilobytes partitions. This update extends the MAX_BLOCK_SIZE value to 4 kilobytes to allow for disks that use the advanced format. (BZ#871579)

This update also adds the following enhancement:

  • This update adds VLAN Tag support for network boot and installation to allow multiple VLANs in a bridged network to share the same physical network link but maintain isolation. (BZ#822657)

All users of yaboot are advised to upgrade to these updated packages, which fix this bug and add this enhancement.

Solution

Before applying this update, make sure all previously-released errata relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/knowledge/articles/11258
