RE: Getting ext3 up and running



I forgot an essential initial step and final step, as initrd is a compressed ext2 file system on file, sorry.
The steps are:

cp /boot/initrd.xxx /boot/initrd.xxx.bck
gzip -dc /boot/initrd.xxx > /tmp/initrd.xxx
mkdir /tmp/initrd_loop
mount -o loop /tmp/initrd.xxx /tmp/initrd_loop
cd /tmp/initrd_loop 

see the modules loaded by linuxrc script and corresponding .o files in lib directory

remove the modules unneeded and corresponding insmod command in linuxrc

umount /tmp/initrd_loop

verify if size is affordable

gzip -c /tmp/initrd.xxx > /boot/initrd.xxx

if you have grub you are done, else run lilo

reboot
sorry

How do I do this?
