Debian 2.6.7-custom and reiser4[]

I may have made some mistakes here, I typed the whole thing up and the wiki timed out, losing all of my edits so I kinda rushed through the 2nd time.

Note: You should not mix versions. That is you shouldn't use an snapshot to build a kernel, then use stable *.exes with it... This is very-likely to cause an reboot or plain not work. If you build a kernel from a version's source, be sure to use that versions binaries.

Download the following[]

stop any colinux instances that are running.
backup your .xml config file
backup your vmlinux file
(Optional) backup your vmlinux-modules.tar.gz file
install the exe from the snapshot to a different directory than your working version
copy your xml config over and make appropriate changes as needed.
make sure you can boot from the snapshot vmlinux.

edit /etc/apt/sources.list change stable to sarge
run: apt-get update
run: apt-cache search kernel ||grep 2.6.7
run: apt-get install kernel-source-2.6.7
run: gcc –-version
- If your version is 2.9xx run: apt-get install gcc-3.3
run: cd /usr/src; tar –jxvf <kernel source>
- this will be in the /usr/src dir if you grabbed it with apt
- check to see if you have kernel headers for the kernel version your trying to compile. something like dpkg -S kernel-head||wc -l
run: bunzip2 <reiser4 archive>
copy the <colinux snapshot *from .tar.gz*>\patch\linux file some where on your colinux instance.
run: ln –s kernel-source-2.6.7 linux
run: cd /usr/src/linux
run: patch –p1 < colinux snapshot\patch\linux
run: patch –p1 < <reiser4 vanilla kernel patch>

make mrproper
copy the <colinux snapshot\conf\linux-config from .tar.gz> to /usr/src/linux/.config
run: make menuconfig
- tweak here at your own risk, you really just want to check for reiser4 support.
- you can edit the Makefile and add your custom kernel extension if you like here as well.
run: make vmlinux
- go get some coffee, check for make errors when done. If you get them one of us has done something wrong. You should have a vmlinux file 2.9MB at the top level directory (e.g: /usr/src/linux/vmlinux). Files with the name "vmlinux" in directories /usr/src/linux/arch/i386/boot or /usr/src/linux/arch/i386/boot/compressed are the wrong ones.
run: make modules modules_install
- If you want to create an vmlinux-modules.tar.gz, do INSTALL_MOD_PATH=<some path>, then tar/gzip the modules installed in that path into vmlinux-modules.tar.gz. Note that you need to tar inside that path (e.g. ./lib in /usr/src/modules/, and not /usr/src/modules/ itself).
- get more coffee if you need it.

make sure you’ve backed things up.
copy the vmlinux file from /usr/src/linux to your windows partition (* not good to overwrite the running copy *).
run: shutdown –h now
- this will bring your instance to powerdown state. If you didn’t know that, you should think twice about kernel hacking.
run: colinux-daemon.exe --remove-driver && colinux-daemon.exe --install-driver
- Sometimes I have found that running the --remove-driver && --install-driver twice in a row prevents a reboot.
- You can, also, use colinux-daemon --status-driver to see if the driver is up and functioning correctly.
wait for your disks to sync, I had 3 reboots before I had a working kernel to boot.
try to start it up, if it boots you need to make the reiser4 fs tools and you're off to the races.

Do not set CONFIG_REGPARM (this will make your host system reboot immediately when trying to start such a kernel).

If you want to be able to boot a native/non-customized FC4 installation, you'll need a few features enabled that aren't in the default kernel:

Enable CONFIG_HOTPLUG (under "General setup", called "Support for hot-pluggable devices")
Enable CONFIG_MD (under "Device Drivers", "Multi-device support", top option) if using LVM (also see CoLinuxNativeRAID)
Enable CONFIG_EXT3_FS_XATTR (under "File Systems", "Ext3 extended attributs")
Enable CONFIG_EXT3_FS_SECURITY (just below)
Enable CONFIG_SECURITY_SELINUX (under "Security options", called "NSA SELinux support") and all sub-options

You'll also need to use the Fedora mkinitrd tool to make an initrd.gz file (use all the --no-whatever options) and set up coLinux to use that.
