   - Add losetup to initramfs.
   - Do mounting.
+===== Useful links =====
+  - Useful link regarding knoppix [[http://www.knoppix.net/wiki/Knoppix_Remastering_Howto]]
+  - Reference for modifying minirt24 [[http://www.knoppix.net/wiki/Knoppix_Remastering_Howto#For_5.3.1_the_file_system_in_minirt_changed_to_ramfs.]]
+===== Following Example =====
+Following the example from [[http://httpfs.sourceforge.net/net_boot.htm]], but facing few problems.
+  - httpfs is failing with error
+<code>
+fusermount: failed open /dev/fuse : no such file or directory
+</code>
+When I did //ls// on ///dev/fuse// I got following output
+<code>
+/dev/fuse ??
+</code>
+Note: the //ls// used in this case is from initramfs and hence may not handle extreme cases properly.\\
+==== Solution ====
+It seems, I need to create ///dev/fuse// myself.
+When I did
+<code>
+# ls -l /KNOPPIX/dev/fuse
+crw-rw-rw- 1 root root   10, 229 May 22 2006 /KNOPPIX/dev/fuse
+</code>
+and created the node with
+<code>
+mknod fuse c 10 229
+</code>
+with this, I am able to mount the remote KNOPPIX.
+===== loading KNOPPIX over HTTP  =====
+if I start DSL and if does not find the KNOPPIX anywhere, then it gives a emergency shell.
+I have written a following script that can be run from that shell and it will load the KNOPPIX on /cdrom/
+<code>
+#!/static/sh
+insmod /modules/crc32.o
+insmod /modules/8390.o
+insmod /modules/mii.o
+insmod /modules/ne2k-pci.o
+insmod /modules/pcnet32.o
+insmod /modules/r8169.o
+insmod /modules/e100.o
+insmod /modules/e1000.o
+insmod /modules/sis900.o
+insmod /modules/via-rhine.o
+insmod /modules/8139too.o
+insmod /modules/af_packet.o
+ifconfig lo 127.0.0.1 up
+ifconfig eth0 up
+udhcpc -s /static/udhcpc.sh 1
+insmod /modules/fuse.o
+echo "testing networking"
+mkdir /ntest
+httpfs http://145.116.233.189/reach /ntest
+echo "checking content"
+cat /ntest/reach
+echo "mounting KNOPPIX"
+mkdir /cdrom/KNOPPIX
+httpfs http://145.116.233.189/KNOPPIX /cdrom/KNOPPIX
+</code>
+This script is invoked automatically from linuxrc.\\
+I have also added the busybox in ///static/busybox// and it supports meny commands.\\
+Networking can be tested with __wget__ but one need to give IP address as URL's are not supported right now.
+<code>
+# wget http://145.116.233.189/reach
+# cat reach
+# mount
+rootfs / rootfs rw 0 0
+/dev/root.old / ext2 rw 0 0
+/proc /proc proc rw 0 0
+/dev/pts /dev/pts devpts rw 0 0
+httpfs /ntest fuse rw,nosuid,nodev,user_id=0,group_id=0 0 0
+httpfs /cdrom fuse rw,nosuid,nodev,user_id=0,group_id=0 0 0
+</code>
+It shows that KNOPPIX is available and __networking__ is working fine\\
+===== Mounting the KNOPPIX =====
+Now, one of the question is when do I call loader.sh from within linuxrc?\\
+Here is the code for [[http://pastebin.com/f265d01b0|linuxrc]]\\
+My guess is that I just need to find correct place, and then it should happen automatically.\\
+Finally, I got it working.
+the modified __linuxrc__ file is [[http://pastebin.com/f5eb77a27|here]].\\
+and latest one which works with [http://rom.etherboot.org/share/pravin/pxeknife/]] is [[http://paste.etherboot.org/?page=view&id=1244928477|here]]
+===== Test the linux over HTTP =====
