The filenames don't matter, but the contents of the file are also
UTF-8, and depending on the default encoding of the Python
interpreter, this can fail on non-ASCII characters in the
file. Set the encoding explicitly while reading and writing
the NetworkManager configuration files.
FIXES#1848
Read, then write, the NM file. Add a note about how we might
handle this better. Rename live_user() function to give it
a verb (and avoid UnboundLocal when using a variable of the same name).
- point to main Calamares site in the 'part of' headers instead
of to github (this is the "this file is part of Calamares"
opening line for most files).
- remove boilerplate from all source files, CMake modules and completions,
this is the 3-paragraph summary of the GPL-3.0-or-later, which has
a meaning entirely covered by the SPDX tag.
In spite of there being considerable documentation sometimes in the
config file, we go with CC0 because we don't want the notion of
'derived work' of a config file.
The example `settings.conf` is also CC0. Add some docs to
it while we're at it.
- a handful of modules had an unused *requires* key in module.desc;
this is probably from previous intentions around
prerequisites-testing. Since the settings were empty anyway,
they have been removed.
- [unpackfs] Compacted the way *requiredModules* list is written
- Remaining modules [networkcfg] [openrcdmcryptcfg] [rawfs] with
code that throws on bad configuration. Replace with meaningful
error messages, to better check cases of SyntaxError &c.
