I use the following to autobuild a simple UML for testing Openswan

---
#!/bin/sh


# Where am I?
ROOT=/code/uml

# Location of sources (Kernel, umlfreeroot, Openswan, etc...)
SOURCE=${ROOT}/source
BUILD=${ROOT}/build


# Set these to your versions
KERNEL_VERSION=2.6.8.1
UML_PATCH_VERSION=1
UML_ROOT_VERSION=19.0
OPENSWAN_VERSION=2.2.0


#
# Probably don't need to change anything else below this line
#
UML_ROOT_FILE=${SOURCE}/umlswanroot-${UML_ROOT_VERSION}.tar.gz
KERNEL_FILE=${SOURCE}/linux-${KERNEL_VERSION}.tar.bz2
UML_PATCH_FILE=${SOURCE}/uml-patch-${KERNEL_VERSION}-${UML_PATCH_VERSION}.bz2
OPENSWAN_FILE=${SOURCE}/openswan-${OPENSWAN_VERSION}.tar.gz


rm -rf ${BUILD}/linux-${KERNEL_VERSION}
rm -rf ${BUILD}/root-${UML_ROOT_VERSION}
rm -rf ${BUILD}/openswan-${OPENSWAN_VERSION}

mkdir -p $BUILD
cd $BUILD
# Build a kernel
tar -xjf ${KERNEL_FILE}
cd linux-${KERNEL_VERSION}
bzcat ${UML_PATCH_FILE} | patch -p1
cp ${ROOT}/umlconfig .config
make ARCH=um linux
cp linux ${BUILD}
chmod 755 ${BUILD}/linux
cd $BUILD
tar -xzf $UML_ROOT_FILE

# fix UML Filesystem if needed

tar -xzvf $OPENSWAN_FILE
cd openswan-${OPENSWAN_VERSION}
make DESTDIR=${BUILD}/root-${UML_ROOT_VERSION} programs install

cd $ROOT

echo "You now have a 2.6 Kernel, UML rootfs, and Openswan ready to go"

umlswanroot-19.0.tar.gz is now on www.openswan.org/code too, and it 2.6
ready (thanks mcr!)
