PyParted and a large rewrite of the underlying partitioning (#1604)
* Invert mypy files * Add optional pre-commit hooks * New profile structure * Serialize profiles * Use profile instead of classmethod * Custom profile setup * Separator between back * Support profile import via url * Move profiles module * Refactor files * Remove symlink * Add user to docker group * Update schema description * Handle list services * mypy fixes * mypy fixes * Rename profilesv2 to profiles * flake8 * mypy again * Support selecting DM * Fix mypy * Cleanup * Update greeter setting * Update schema * Revert toml changes * Poc external dependencies * Dependency support * New encryption menu * flake8 * Mypy and flake8 * Unify lsblk command * Update bootloader configuration * Git hooks * Fix import * Pyparted * Remove custom font setting * flake8 * Remove default preview * Manual partitioning menu * Update structure * Disk configuration * Update filesystem * luks2 encryption * Everything works until installation * Btrfsutil * Btrfs handling * Update btrfs * Save encryption config * Fix pipewire issue * Update mypy version * Update all pre-commit * Update package versions * Revert audio/pipewire * Merge master PRs * Add master changes * Merge master changes * Small renaming * Pull master changes * Reset disk enc after disk config change * Generate locals * Update naming * Fix imports * Fix broken sync * Fix pre selection on table menu * Profile menu * Update profile * Fix post_install * Added python-pyparted to PKGBUILD, this requires [testing] to be enabled in order to run makepkg. Package still works via python -m build etc. * Swaped around some setuptools logic in pyproject Since we define `package-data` and `packages` there should be no need for: ``` [tool.setuptools.packages.find] where = ["archinstall", "archinstall.*"] ``` * Removed pyproject collisions. Duplicate definitions. * Made sure pyproject.toml includes languages * Add example and update README * Fix pyproject issues * Generate locale * Refactor imports * Simplify imports * Add profile description and package examples * Align code * Fix mypy * Simplify imports * Fix saving config * Fix wrong luks merge * Refactor installation * Fix cdrom device loading * Fix wrongly merged code * Fix imports and greeter * Don't terminate on partprobe error * Use specific path on partprobe from luks * Update archinstall/lib/disk/device_model.py Co-authored-by: codefiles <11915375+codefiles@users.noreply.github.com> * Update archinstall/lib/disk/device_model.py Co-authored-by: codefiles <11915375+codefiles@users.noreply.github.com> * Update github workflow to test archinstall installation * Update sway merge * Generate locales * Update workflow --------- Co-authored-by: Daniel Girtler <girtler.daniel@gmail.com> Co-authored-by: Anton Hvornum <anton@hvornum.se> Co-authored-by: Anton Hvornum <anton.feeds+github@gmail.com> Co-authored-by: codefiles <11915375+codefiles@users.noreply.github.com>
