1.124.1. RHBA-2010:0242: bug fix update

Update module-init-tools packages that fix several bugs are now available.
The module-init-tools package includes various programs needed for automatic loading and unloading of modules under 2.6 and later kernels, as well as other module management programs. Device drivers and filesystems are two examples of loaded and unloaded modules.
The updated packages fix the following bugs:
* on Xen systems with more than one detected serial device, a race condition could occur between simultaneously executed modprobe module loading utilty commands if the Xen Hypervisor was blocking access or was misconfigured. The updated packages implement a read-only filesystem locking mechanism that prevents modprobe race conditions from occurring. (BZ#430942)
* on systems where a driver update was removed and no compatible driver update exists after the removal, the weak-module post-installation scripts created symbolic links to the location of the deleted driver. This caused problems with driver updates, and using the weak-module utility. The updated packages ensure post-installation scripts create valid symbolic links to installed drivers. (BZ#477089)
* on systems running Xen hypervisor compatible kernels, where the kernel is used as a guest kernel (Dom0) and not as a host kernel (DomU), the scripts that perform module post-install checks could re-generate an incorrect bootloader entry for the system. In some cases, this prevented the sytem from booting. The updated packages implement revised post-install checks, which prevent this scenario from occurring. (BZ#509568)
All module-init-tools users are advised to upgrade to these updated packages, which resolve these issues.
