# There are several issues with mounting of configuration files into container.
# One of them is related to files "update" problem with live container (without container re-creation).
# Tools (ansible, vim) usually creates new file and then rename it "atomically" (this assigns new "inode" to file).
# Docker binds "inode", not a file name, so that changes are not updated in the container.
# Workaround is mounting file "clones" instead of original files.
