I don't know enough about Docker images to decide that. In case the
Docker's `$HOME` directory can be easily deleted on a clean-up,
nothing needs to be changed IMHO. Otherwise it is trivial to set the
`$TEXMFVAR` environment variable to an appropriate temporary directory
before a LilyPond documentation build.
