You may safely nuke everything that is not your Cygwin installation.
If you want to maintain a cache of downloaded packages elsewhere, copy
setup<arch>.exe to a dedicated location before starting an
upgrade/installation.
Alternatively, this script may be of help.
#!/bin/sh
# Cygwin upgrade helper script.
# Usage:
#
# install-cygwin.sh [ ports ]
#
# If you intend to use it for new installs, you will need minimal bootstrap
# including POSIX shell interpreter and wget utility.
#
# You will have to edit the script to provide mirror URL of your choice.
#
# The script assumes existing installation of the same architecture as
# the host operating system.
# If you want to install 32-bit Cygwin on 64-bit host, override
# $ARCH with value other than "x86_64".
# F.e.
#
# ARCH=x86 ./install-cygwin.sh
# Mirror URL - don't include trailing slash!
MIRROR="${MIRROR:-http://example.com/Mirrors/sources.redhat.com/cygwin}";
# System architecture.
ARCH="${ARCH:-$(uname -m)}"
# Localization is fine... as long as you don't show it to other people.
export LANG=C
if [ "$ARCH" != "x86_64" ]; then
ARCH=x86
fi
wget -N "http://cygwin.com/setup-${ARCH}.exe";
if [ "$1" = "ports" ]; then
KEYS="-K http://cygwinports.org/ports.gpg -s ""${MIRROR%%/}ports/"
shift
fi
./setup-${ARCH}.exe -O -s "${MIRROR%%/}/" $KEYS $* &
