Removed x-setup from local.start and added in symlinks for gconf, portage profiles (for installer) and /var/db.  Added a touch for root's .bashrc for baselayout and removed /etc/startx from the environmental type.  Commented unmerge of sources in kmerge.sh, as they should be unmerged by the spec file.  Changed livecdfs-update.sh to setup /etc/hosts properly, allow wheel users to use sudo with no password, mount /usr/lib/X11/xkb/compiled as tmpfs for X, use the latest pci.ids and usb.ids from portage, and create /lib/firmware if it doesn't exist.  Commented unmerge of genkernel in post-kmerge.sh, as it should be unmerged by the spec file.  Fixed typo in snapshot_target.py.  Made gconfd check in livecd-stage1.sh work if more than one gconfd-2 is running.  Added a gcc-config fix to stage1-chroot.sh.  Changed gcc-config check in stage1-preclean2-chroot.sh to ensure gcc-config is an executable.
