The idea behind this is to test whether you can re-compile your system (without changing anything) and then successfully reboot - if this works then you know that you are correctly set-up for the real thing. Thanks to ^thehatsrule^ for the help.
This was tested using DSL 3.0.1
Back-up your USB stick before proceeding at your own risk.
Materials required
-----------------
Download gcc-2.95.dsl, gcc1-with-libs.dsl & gnu-utils.dsl from the DSL repository
Download linux-2.4.26.tar.gz from "www.kernel.org" or mirror sites
Obtain knoppix 3.4 CD, download KNOPPIX_V3.4-2004-05-04-EN.iso from "http://www.pctips.pl/ftp/linux_342/Knoppix%203.4.html" or download kernelsource.dsl
Preparation
-----------
load required dsl packages:
# mydsl-load /path-to-file/gcc-2.95.dsl
# mydsl-load /path-to-file/gcc1-with-libs.dsl
# mydsl-load /path-to-file/gnu-utils.dsl
Create a directory for the kernel sources owned by user dsl:
# mkdir /usr/src
# chown dsl /usr/src
Copy the kernel sources to the new directory and un-pack them:
# cp /path-to-file/linux-2.4.26.tar.gz /usr/src/
# cd /usr/src
# tar -xzvf linux-2.4.26.tar.gz -C /usr/src
# rm linux-2.4.26.tar.gz
Copy the knoppix patch and configuration files from the CD or iso or dsl:
Either
# mkdir /ramdisk/image
# mount /path-to-file/KNOPPIX_V3.4-2004-05-04-EN.iso /ramdisk/image -t iso9660 -o loop,ro
# mkdir /ramdisk/unpack
# mount /ramdisk/image/KNOPPIX/KNOPPIX /ramdisk/unpack -t iso9660 -o ro,loop=/dev/cloop50
# cp /ramdisk/unpack/usr/src/* /usr/src
# cp /ramdisk/unpack/usr/src/linux-2.4.26/.* /usr/src
# umount /ramdisk/image
# umount /ramdisk/unpack
# rmdir /ramdisk/image
# rmdir /ramdisk/unpack
or
# mkdir /ramdisk/unpack
# mount /mnt/your-cd-drive/KNOPPIX/KNOPPIX /ramdisk/unpack -t iso9660 -o ro,loop=/dev/cloop50
# cp /ramdisk/unpack/usr/src/* /usr/src
# cp /ramdisk/unpack/usr/src/linux-2.4.26/.* /usr/src
# umount /ramdisk/unpack
# rmdir /ramdisk/unpack
or
# mkdir /ramdisk/unpack
# cp /path-to-file/kernelsource.dsl /ramdisk/unpack
# cd /ramdisk/unpack
# tar xvzf kernelsource.dsl
# cp /ramdisk/unpack/usr/src/* /usr/src
# cp /ramdisk/unpack/usr/src/linux-2.4.26/.* /usr/src
# rm -r /ramdisk/unpack
Apply the knoppix patch to the kernel sources:
# cd /usr/src
# patch -p1 -d linux-2.4.26 < knoppix-kernel.patch
Note that at this point in a "real re-compile" you would be ready to apply a kernel patch but, since this is a test, omit this step.
Recompile
---------
Prepare sources for re-compilation:
# cd /usr/src/linux-2.4.26
# make mrproper
Load the knoppix kernel configuration - note that at this point in a "real re-compile" you would be ready to change the kernel configuration, add modules, etc but, since this is a test, just load the knoppix kernel configuration and then save it.
# make menuconfig
Go to the last but one menu item <load an alternative configuration file>
tab to <select> and hit enter
replace text with "/usr/src/.config"
tab to <OK> and hit enter
tab to <exit> and hit enter (you will see "Do you wish to save your new kernel configuration?")
tab to <yes> and hit enter
Build dependencies and cleanup:
# make dep
# make clean
Build kernel boot image and copy to /boot:
# make bzImage
# make install
Note that at this point, if you had added additional loadable modules in a "real re-compile", you would issue the commands "make modules" and "make modules_install", but, since this is a test, omit this step.
Prepare to reboot
-----------------
copy kernel boot image to the root directory of your USB stick:
# cp /boot/vmlinuz-2.4.26 /path-to-boot-usb-root-dir/vmlinuz
make the boot image writeable (required for USB boot):
# rdev -R /path-to-boot-usb-root-dir/vmlinuz 0
Reboot
-------
Reboot as normal but when the first DSL screen appears requesting boot options, enter vmlinuz and hit enter.
If eveything went OK, DSL should now start up as usual.
If everything didn't go OK, then you could try deleting the boot option "quiet" from your syslinux.cfg file to get some clues as to what might have gone wrong...
