Small correction to xserver.nix for compiz; also nixos-checkout now creates services where it should be. svn path=/nixos/trunk/; revision=9578 2007-11-05 09:33:12 +01:00			`if test -e services -a ! -e services/.svn; then`

* The CD is now a true live CD: you can run Nix operations in it thanks to unionfs. For instance, nix-env and nixos-rebuild work. The tricky part was to build a Nix database (in the tmpfs/unionfs) which is now necessary to prevent store paths on the CD from being deleted right away because they otherwise wouldn't be valid. * nixos-install: use the /etc/nixos/configuration.nix from the target file system (don't copy it anymore). Since the user is supposed to mount the target file system on /mnt anyway, we may as well require that configuration.nix is placed in /mnt/etc/nixos. This also makes upgrading / reinstalling much easier, since it will automatically use the right configuration.nix. svn path=/nixos/trunk/; revision=10399 2008-01-30 02:28:56 +01:00			`# Add a few required symlink.`
