Public bug reported:
Ephemeral containers (but not non-ephemeral ones) have all of their
/proc/*/maps entries prefixed with "/rootfs". One problem this causes
is that graphviz uses /proc/self/maps to locate its plugins. That means
that some of the plugins can not be loaded.
To reproduce the problem with dot, run this command:
dot -Tcmapx < /dev/null
No output is expected, however because of the bug this output is
produced:
Format: "cmapx" not recognized. Use one of: dia hpgl mif mp pcl pic
vtx
A workaround for the problem with graphviz is to make the plugins
available at the path it is expecting:
mkdir -p /rootfs/usr/lib
ln -s /usr/lib/graphviz /rootfs/usr/lib/graphviz
