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.

|
|
supported on Version 7 or BSD versions.

The SVr4 menu library documentation specifies the <STRONG>item_count</STRONG> error
|
|
value as -1 (which is the value of <STRONG>ERR</STRONG>).
