# On most systems I've used a link to /proc/kcore is placed at
# /dev/core. However, on TravisCI we also see it at /dev/kcore.
#
# Since we are using this file to test some properties of symlinks, we
# don't particularly care where it is, so here we use /dev/kcore if it
# exists and otherwise fall back to /dev/core.
