Re: [Minios-devel] [UNIKRAFT/PYTHON3 PATCH v3 11/14] Makefile.uk: Add rule for creating root filesystem

[Felipe Huici <Felipe.Huici@xxxxxxxxx>]

Hi Costin,

It might be good to create the directory if one is not there, that would be 
more user friendly (the README.md is a bit vague about this).

    The Python interpreter needs a filesystem where to keep its libraries. This
    patch creates a Python virtual environment and installs the Python 3 
standard
    library in /lib/python3.7 directory. For creating the filesystem the 
following
    command has to be run:
    
    $ make python-rootfs path=<directory>
