RHBA-2013:0087 - Bug Fix Advisory

Topic

Updated grub packages that fix three bugs are now available for Red Hat
Enterprise Linux 5.

Description

The GRUB utility is responsible for booting the operating system kernel.

This update fixes the following bugs:

• The grub documentation contained incorrect information about the planned but

unimplemented "grub-set-default" command; the "savedefault" command has been
implemented instead, providing similar functionality. This update corrects the
grub documentation that now reflect only those commands which have been
implemented in GRUB. (BZ#212649)

• Prior to this update, the "grub-install" command was matching only against one

letter after the "sd" string in the disk's device path name. Consequently, disks
named "sdaa" and higher were not recognized as disks. The matching expression
has been changed and now the "grub-install" command matches against any number
of reasonable characters after the "sd" string in the disk's device path name.
(BZ#782096)

• Previously, the number of disks was hard-coded to a maximum of 8. As a

consequence, no more than 8 devices could be used. This update has changed the
definition of allowed disks to a maximum of 128 and now up to 128 devices can be
used. (BZ#829228)

All users of GRUB are advised to upgrade to these updated packages, which fix
these bugs.
