More questions:

What about the scripts in tails/auto? At least auto/build and auto/config are quite complex shell scripts.

Some of the scripts source functions or configuration variables from other shell scripts. All the scripts in config/binary_local-hooks source

“${LB_BASE:-/usr/share/live/build}”/scripts/build.sh

and scripts in chroot_local-hooks source

/usr/share/amnesia/build/variables (created by ./auto/build)

or

/usr/local/lib/tails-shell-library/*

We certainly don’t want to maintain a bash and a Python version of config files and the library. Either we keep all scripts that use these in bash or we convert the library and all the scripts that use it to Python. But the tails-shell-library is also used in many other places, so it might not be possible to move them to Python.

Some scripts that are sourced by other scripts are

10-tbb:. /usr/local/lib/tails-shell-library/tor-browser.sh
11-localize_browser:. /usr/local/lib/tails-shell-library/tor-browser.sh
11-localize_browser:. /usr/local/lib/tails-shell-library/common.sh
11-localize_browser:. /usr/local/lib/tails-shell-library/localization.sh
11-localize_browser:. /etc/amnesia/environment
13-override-tbb-branding:. /usr/local/lib/tails-shell-library/tor-browser.sh
20-xul-ext_symlinks:. /usr/local/lib/tails-shell-library/tor-browser.sh
98-remove_unwanted_files:. /usr/share/amnesia/build/variables

I’d love to see them ported to Python. Beware though: I suspect that live-build (itself written in shell) sources these scripts, so it might be that we need at least a thin shell wrapper if we’re going to port most of that code to Python.

Agreed.

The same config files could be usable both in Python and shell though, if they only contain static data encoded in some standard format.

I think that those should be ported to Python eventually: chroot local hooks prompted this effort, see for example our initial porting example (feature/11198-python-scripting) :)
