Slackware 13.0slackware-13.0

Wed Aug 26 10:00:38 CDT 2009
Slackware 13.0 x86_64 is released as stable!  Thanks to everyone who
helped make this release possible -- see the RELEASE_NOTES for the
credits.  The ISOs are off to the replicator.  This time it will be a
6 CD-ROM 32-bit set and a dual-sided 32-bit/64-bit x86/x86_64 DVD.
We're taking pre-orders now at store.slackware.com.  Please consider
picking up a copy to help support the project.  Once again, thanks to
the entire Slackware community for all the help testing and fixing
things and offering suggestions during this development cycle.
As always, have fun and enjoy!  -P.

+# With a generic kernel, you need to load the modules needed to mount the
+# root partition.  This might mean a SCSI, RAID, or other drive controller
+# module, as well as the module to support the root filesystem.  Once the
+# root partition is mounted all the other modules will be available so you
+# don't need to load them here.
+#
+# Config files used by this script:
+#
+# /rootdev   Contains the name of the root device, such as: /dev/hda1 
+#
+# /rootfs    Contains the root filesystem type, such as: xfs
+#
+# /initrd-name    Contains the name of the initrd file.
+#
+# Optional:
+# /load_kernel_modules   A script that uses insmod to load the desired
+#            modules.  If this file is not present, all the modules
+#            in /lib/modules/`uname -r`/ will be loaded in the usual
+#            sorted order.  If you need to load the modules in a
+#            certain order, or if the modules need extra options,
+#            then use a load_kernel_modules script.
+#
+#            There's an example in here.  To actually use it, you'll
+#            need to make it executable:  
+#
+#                chmod 755 load_kernel_modules
