1. Copy "resolv.conf" before running apt-get update / yum update.
Without this DNS is probably not available/working.
2. Copy /etc/sudoers from the host, if we're installing sudo.
Source common.sh from the parent directory if the global installation
isn't found.
This allows "make test" to succeed *before* the tools are installed.
Added to the repository. These are almost straight copies of the
previous hook scripts except they are now Debian-specific.
They also each log their start and finish and optional information
via the use of the ../common.sh file.
No major changes anticipated.
