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.

+# Added support to bail out if kernel modules are requested for a kernel
+# version that is not installed (thanks to Eric Hameleers), be more
+# verbose about showing modules added to the initrd (thanks to
+# Ellington Santos), and if "mount" returns /dev/root as the root device,
+# use readlink to resolve the device pointed to by the /dev/root
+# symlink, changed modprobe to use --ignore-install to avoid catching
+# custom "install" lines and causing /sbin/modprobe to be copied to the
+# initrd (thanks to Ken Milmore).
+# Of course, license terms remain unchanged.

+print_usage() {
+  cat << EOF
+Usage: mkinitrd [OPTION]
+
+mkinitrd creates an initial ramdisk (actually an initramfs cpio+gzip
+archive) used to load kernel modules that are needed to mount the
+root filesystem, or other modules that might be needed before the
+root filesystem is available.  Other binaries may be added to the
+initrd, and the script is easy to modify.  Be creative.  :-)
+
+  -F      Use the contents of /etc/mkinitrd.conf (optional)
+          If this is used in conjunction with any other options passed
+          on the command line, the command-line options will override
+          the config file options.  See mkinitrd.conf(5) for details.
+  -c      Clear the existing initrd tree first
+  -f      Filesystem to use for root partition (must be used with -r)
+  --help  Display this message
+  -h      Device to resume from hibernation. Needs to be the name of
+          the swap partition holding the hibernation image.
+  -k      Kernel version to use
+  -l      Custom keymap to load. Like, 'nl' or 'de-latin1-nodeadkeys'
+  -m      A colon (:) delimited list of kernel modules to load.
+          Additional options may be added to use when loading the
+          kernel modules (but in this case the entire list must be
+          wrapped with double quotes).  Any dependencies of requested
+          modules will also be added to the initrd.
+  -o      Output image (default /boot/initrd.gz)
+  -r      Root partition device (must be used with -f)
+  -s      Initrd source tree (default /boot/initrd-tree/)
+  -w      Time to wait until all disks are detected
+  -C      Use cryptsetup to unlock the underlying device of an
+          encrypted root filesystem (must be used with '-r' parameter).
+          Two scenarios are possible. (1) root filesystem was created on the
+          encrypted disk/LVM partition, example:
+            -C /dev/sda2 -r cryptroot
+          where /dev/sda2 is the encrypted partition and
+          the actual root device name in /etc/fstab is:
+            /dev/mapper/cryptroot
+          (2) the encrypted partition contains a LVM volume which holds the
+          root filesystem, example:
+            -C /dev/sda2 -r /dev/vg/root
+          where /dev/sda2 is the encrypted partition and
+          the actual root device name in /etc/fstab is:
+            /dev/vg/root
+  -L      Add support for LVM partitions
+  -R      Add support for RAID partitions
+  -V      Display version number
+
+A simple example:  Build an initrd for a reiserfs root partition:
+
+  mkinitrd -c -m reiserfs
+
+Another example:  Build an initrd image using Linux 2.6.29.3-smp kernel
+modules for a system with an ext3 root partition on /dev/hdb3:
+
+  mkinitrd -c -k 2.6.29.3-smp -m mbcache:jbd:ext3 -f ext3 -r /dev/hdb3
+
+Note that if you are already logged in with /dev/hdb3 as your /
+partition, and it is running ext3, this command works just the same:
+
+  mkinitrd -c -m ext3
+
+If run without options, mkinitrd will rebuild an initrd image using
+the contents of the $SOURCE_TREE directory, or, if that directory
+does not exist it will be created and populated, and then mkinitrd
+will exit.
