I mean Chimera is using FreeBSD userland, and they expressed why GNU coreutils used by most distro have “problem”. Since we are talking about BSD. (OpenBSD’s userland is less in feature and it is cleaner)

(so that’s bring an advantage in security lol)

While coreutils may seem lightweight enough to not cause any issues already, there are some specific reasons the system uses a BSD-derived userland. The primary one is probably that the code of the BSD versions is overall much cleaner and easier to read. There are no cursed components such as gnulib, the codebase is leaner, and more aligned with the project’s goals.
