# Chooses a function and invokes it depending on the O/S distribution. # Invoke a function, with a primitive dynamic dispatch based on the distribution.

# Example: # Format: `invoke "function" [--optional]`.

# A target function must exist, otherwise a error is raised, unless `--optional` is specified.
# `--optional` is useful when a step is specific to a single distribution, e.g. Debian's root password.
