@SuperDicq @hj @hakui @latein @sun @Wiz @HatkeshiatorTND >Alpine is not a GNU/Linux distribution, because it uses musl and busybox instead of glibc and coreutils.
As I pointed out, Alpine uses GNU coreutils *by default* - there is just an *installer available* without it.

BusyBox contains a nontrivial amount of GNU code.

The typical use case of Alpine GNU/Linux consists of installing glibc; https://gist.github.com/larzza/0f070a1b61c1d6a699653c9a792294be or installing gcompat (pretty much copy-pasting a few things from glibc that musl lacks), or installing GNU with glibc in a chroot; https://wiki.alpinelinux.org/wiki/Software_management?useskin=vector#Running_glibc_programs

@EdBoatConnoisseur @HatkeshiatorTND @latein @SuperDicq @hj @sun @Wiz @hakui BusyBox is not limited to an implementation of POSIX compliant utils.

It is also a defective clone of GNU packages like; bc, tar, less, wget, strings & patch
as well as defective clones of programs like; hdparm, powertop, ntpd & minicom (microcom)
as well as a tiny init and webserver.

The whole idea of BusyBox was to make a clone of GNU that goes in a single binary, for constrained embedded environments, by copy-pasting a bunch of files from GNU and other projects and removing pretty much all of the useful functionality to make the binary smaller - as anything recent is no longer constrained anymore (you have 1GB+ RAM), you're far better off using proper GNU/Linux than defective GNU/Linux.

GNU coreutils only has relevance to the utils parts of BusyBox - but of course every last coreutils program is far superior to BusyBox's implementation.
