This helps with a situation when some applications do not allow mounting individual files, but whole directories. In that case users could mount `/config` directory with a single file, `config.toml`: `-v /path/to/dir:/config`. Also, there is a backward compatibility to using a single `/config.toml`

# this is done for backward compatibility: before that we mounted a config
|
|
# into /config.toml. Some application allow mounting directories only,
|
|
# so it makes problems. So, instead we are going to do 2 steps:
|
|
# 1. Create /config/config.toml as a symlink to /config.toml
|
|
# 2. Force /mtg to use /config/config.toml
|
|
#
|
|
# it helps in both ways: users with directories could use /config directory
|
|
# and overlap a symlink by their bind mount. Old users could continue using
|
|
# /config.toml as a real config.
