9.3.1 Multiple Kernels
It is possible to install multiple kernels side by side. This feature is meant to allow ad-
ministrators to upgrade from one kernel to another by installing the new kernel, verifying
that the new kernel works as expected, then uninstalling the old kernel. While YaST
does not yet support this feature, kernels can easily be installed and uninstalled from
the shell using rpm -i package.rpm.
The default boot loader menus contain one kernel entry. Before installing multiple
kernels, it is useful to add an entry for the extra kernels, so they can be selected easily.
The kernel that was active before installing the new kernel can be accessed as vmlinuz
.previous and initrd.previous. By creating a boot loader entry similar to the
default entry and having this entry refer to vmlinuz.previous and initrd
.previous instead of vmlinuz and initrd, the previously active kernel can be
accessed. Alternatively, GRUB and LILO support wild card boot loader entries. Refer
to the GRUB info pages (info grub) and to the lilo.conf(5) manual page for
details.
9.3.2 Changes with Kernel Modules
The following kernel modules are no longer available:
• km_fcdsl—AVM Fritz!Card DSL
• km_fritzcapi—AVM FRITZ! ISDN Adapters
The following kernel module package was changed internally:
• km_wlan—Various drivers for wireless LAN cards. The madwifi driver for
Atheros WLAN cards from km_wlan was removed. madwifi is available as a
stand-alone package.
For technical reasons, it was necessary to drop support for Ralink WLAN cards. The
following modules were not part of the distribution and will not be added in the future:
• ati-fglrx—ATI FireGL Graphics Cards
• nvidia-gfx—NVIDIA gfx driver
