It's actually used for changing config files based on different network locations, but you could easily adapt it (and I did) for changing any files you want. Basically, you have multiple versions of every file: /etc/resolv.conf.home /etc/resolv.conf.work And quickswitch manages a symlink /etc/resolv.conf which points to the right one depending on what it thinks you want. > a link would be really cool! how about http://engrish.com -it's funny and a good time-waster. quickswitch however is in portage. For your startup scripts, I would use different runlevels. Check out the gentoo wiki, it's the "gentoo-way". Each grub line (assuming you use grub) for each kernel can start it's own runlevel: kernel /vmlinuz-2.6.16-suspend2 softlevel=suspend-sources-runlevel kernel /vmlinuz-2.6.16-ck-r4 softlevel=ck-sources-runlevel and so on. Here's the proviso I mentioned earlier: some ebuilds that install 3rd party kernel modules (ati-drivers, vmware, etc) may not work when you change kernels. Don't ask me why, but I usually have to recompile these ebuilds each time I change kernels, even if I've compiled for that kernel on a previous boot. HTH.
