#
# Note 1: use the eev command (defined in eev.el) and the
# ee alias (in my .zshrc) to execute parts of this file.
# Executing this file as a whole makes no sense.
# An introduction to eev can be found here:
#
# (find-eev-quick-intro)
# http://angg.twu.net/eev-intros/find-eev-quick-intro.html
#
# Note 2: be VERY careful and make sure you understand what
# you're doing.
#
# Note 3: If you use a shell other than zsh things like |&
# and the for loops may not work.
#
# Note 4: I always run as root.
#
# Note 5: some parts are too old and don't work anymore. Some
# never worked.
#
# Note 6: the definitions for the find-xxxfile commands are on my
# .emacs.
#
# Note 7: if you see a strange command check my .zshrc -- it may
# be defined there as a function or an alias.
#
# Note 8: the sections without dates are always older than the
# sections with dates.

# IRC question:
a question about user-mode-linux... I've created an hd image in
/tmp/sarge.hdimg, an ext2 filesystem inside it, mounted it on
/tmp/sarge, initialized it with debootstrap, added umlrun-uml, etc,
and now user-mode-linux seems to run happily when I do "linux
root=/dev/root ubd0=/tmp/sarge.hdimg con=xterm"... but how do I run a
shell inside the uml?
do I need the skas patch in the host kernel?
