Hi, I would like to set up my linux system so that I can operate in two separate environments, hopefully selectable at the lilo boot prompt. I need to change things such as /etc/init.d/network (I still have to look at the recent potato changes here though) /etc/hosts, /etc/networks, /etc/hostname and (slightly trickier) I need to load a different network card driver module. What do others do in this situation? Would chroot help? Regards, Mark.
