3.48. mkinitrd

Bug Fixes

BZ#1006058

A previous fix to a related security issue introduced to the libnss library a new run-time dependency on the libsqlite library. However, libsqlite was not included in the initrd.img file. As a consequence, the kernel verification was not successful and caused the system boot to fail with a kernel panic. With this update, the mkinitrd utility verifies that libsqlite is included when building a new initrd image and the kernel panic no longer occurs.

BZ#978245

Prior to this update, the Advanced Host Controller Interface (AHCI) driver was not included in the initrd.img file. As a consequence, a Red Hat Enterprise Linux 5 guest in some cases failed to boot on a Red Hat Enterprise Linux 7 hypervisor. With this update, installing Red Hat Enterprise Linux 5 as a guest now always includes the AHCI driver, and the guest is therefore able to boot as expected.

BZ#988020

Previously, mkinitrd searched an incorrect path for the cciss block driver device and the findstoragedriver() function could therefore not find cciss in the /sys/block directory. Consequently, the kernel failed to boot after it was updated. This update amends the cciss path and findstoragedriver() is thus able to detect cciss devices correctly. As a result, the kernel now boots as expected.

Enhancement

BZ#472764

In order to simplify the process of adding a new direct access storage device (DASD), running a mkinitrd command without parameters now prompts the user to re-create the initial RAM disk for the currently running kernel in the /boot/ directory.
