Bootstrap install with virtual environment appears not to use a virtual environment

[JeffreyUrban]

When running the bootstrap command with the optional flag -v venv, the command line output shows python packages being installed, but does not show that a virtual environment has been created or is being used.

As run:

curl bootstrap.f0cal.com/master | python3 - --no-sudo --skip-system-packages -v venv git

Problems:

• Users may interrupt the install due to concerns that their system python is being changed.

Suggested change:

• Add a loud message to the script standard output to clarify that the virtual environment is created and used.

For example:

*****************************************************************
* Installing packages to new virtual environment at f0cal/venv/ *
*****************************************************************
