Re: [coLinux-users] help setting up a dual boot system

[Dwight C. <da...@po...>]

Eh, here's the cheap-n-nasty solution I'm using for that....

(colinux 20040622, slackware 10.0)

First thing in /etc/rc.d/rc.S is add at the top

/sbin/mount -o remount,rw /
/etc/rc.d/rc.VerHack
/sbin/mount -o remount,ro /

the contents of rc.VerHack are

#!/bin/sh
# version workarounds.  Bah!

echo "Applying ugly kernel version hacks (colinux vs. real linux)"
/bin/rm /etc/fstab
/bin/rm /etc/lilo.conf
/bin/rm /opt/kde/share/config/kdm/Xservers
/bin/rm /usr/src/linux

if uname -r | grep "co-" ; then
  ln -s /etc/fstab.colinux /etc/fstab
  ln -s /etc/lilo.conf.colinux /etc/lilo.conf
  ln -s /opt/kde/share/config/kdm/Xservers.colinux /opt/kde/share/config/kdm/Xservers
  ln -s /usr/src/linux-2.6.7-co-0.6.2 /usr/src/linux
else
  ln -s /etc/fstab.reallinux /etc/fstab
  ln -s /etc/lilo.conf.reallinux /etc/lilo.conf
  ln -s /opt/kde/share/config/kdm/Xservers.reallinux /opt/kde/share/config/kdm/Xservers
  ln -s /usr/src/linux-2.6.7 /usr/src/linux
fi


Substitute config files as needed for differrences between real hardware and
colinux boot.  This approach has a few downsides, such as possibly borking
system sanity checks at boot time.  Wouldn't want to use anything even vaguely
resembling in a production environment, etc etc.


Hope this helps,
d.c.
