# E-scripts on qemu (and virtualbox).
#
# 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.

<edrx> hi... is this the right syntax for testing an image that
       will be saved in a pen drive?
<edrx> qemu-system-x86_64 -usb -usbdevice
       disk:format=raw:/tmp/pendrive.img
<edrx> I installed grub in that image but when I ask grub to list
       the available disks it doesn't list anything like
       "(usb0)/"...
<edrx> there are a handful of things that I guess that I may be
       doing wrong, but if I rule out the hypothesis that I am
       calling qemu with the wrong arguments then I won't need to
       do real reboots all the time to test the pen drive...
