Red Bear OS is a full fork. All sources must be available from git clone with zero network access. Removed gitignore rules that excluded fetched source trees under recipes/*/source/, local/recipes/kde/*/source/, local/recipes/qt/*/source/, and vendor source trees. Build artifacts (target/, build/, source.tar, *.o, *.so) remain excluded. 127291 files added — kernel, relibc, base, bootloader, pkgar, all KDE/Qt frameworks, mesa, wayland, DRM drivers, and every other recipe source.

# To avoid using a function in bash, you can use the `builtin' or
|
|
# `command' builtins, but neither guarantees that you use an external
|
|
# program instead of a bash builtin if there's a builtin by that name. So
|
|
# this function can be used like `command' except that it guarantees the
|
|
# program is external by first disabling any builtin by that name. After
|
|
# the command is done executing, the state of the builtin is restored.
