# This file contain ALL todos after kernel changes!
# So it is possible for me to remember what I have done to the kernel
# and what I have todo to the kernel and additional modules
#
# so after 'make menuconfig' I must only start 'machkernel' reboot and machkernel, reboot again!
# nothing else.
# This tool works only within the 2.4.X kernel
# 
# I don't need to remember to set up lilo or grub
# alsa
# vpn
# webcam driver
# hpt37x driver
# backup kernel, install a nice new console font.
