Sharing code between scripts

[rollcat]

The general problems are avoiding boilerplate, bootstrapping/setting up the environment, abstracting over OS- or distro-specific details, or providing a library of common functions for other scripts to use.

It might be useful to allow executing a series of commands/scripts over the selected hosts, while retaining the remote working directory contents in between:

judo \
    -s scripts/bootstrap \
    -s scripts/common \
    -s scripts/install-python \
    -c "python --version" \
    some-hosts

Here, scripts/common can rely on scripts/bootstrap having been completed successfully, and scripts/install-python can include a function library exported by scripts/common, for example by running . scripts/common/$(uname) or so.
