Currently, toolbox(1) offers a --verbose option that only shows debug
information from toolbox(1) itself and the error stream of internal
commands. There's no way to further increase the log level of the
internal commands. It's sometimes very useful to be able to get more
detailed logs from Podman.
This adds a new --very-verbose or -vv option that makes this possible.
This should have been implemented as '--verbose --verbose', which
could be conveniently shortened to '-vv'. This is what flatpak(1)
does. However, due to the lack of built-in command line parsing
facilities in POSIX shell, there's no support for multiple short
options expressed as one single argument. eg., '-vy' doesn't expand to
'-v -y'.
Therefore, a separate --very-verbose or -vv option was added to make
things convenient for the user. It's expected that most people will
refer to this as -vv.
If this option is used, every Podman command in the code is run with
'--log-level debug'. Use wisely, Podman can be 'very verbose'.
