Major Description
Here's an excerpt from the Karaf 4 /deployments/karaf/bin/karaf script:
OURPWD=${PWD}
cd "$(dirname "${1}")" || exit 2
LINK=$(readlink "$(basename "${1}")")
while [ "${LINK}" ]; do
echo "link: ${LINK}" >&2
cd "$(dirname "${LINK}")" || exit 2
LINK=$(readlink "$(basename "${1}")")
done
REALPATH="${PWD}/$(basename "${1}")"
cd "${OURPWD}" || exit 2
echo "${REALPATH}"
It saves the initial directory path in OURPWD and attempts to cd back to it later on. On Openshift this starts as /home/jboss. But since we'll be running under an arbitrary UID, the cd switch back to /home/jboss fails:
Executing /deployments/karaf/bin/karaf server ... /deployments/karaf/bin/karaf: line 31: cd: /home/jboss: Permission denied /deployments/karaf/bin/karaf: line 55: ./inc: Permission denied
