Description of problem: The "busybox" binary installed by the busybox-1.35.0-5.fc37.x86_64 package is not statically linked, but instead dynamically linked against the musl libc. I found this *extremely* surprising... especially since the package description says it's static, there's a symlink to the same binary under the name "busybox.musl.static", and there's another package (busybox-shared) that's billed as offering an "alternative" dynamically linked version of busybox. The main utility of busybox, at least in a "big computer" OS like Fedora, is that it's a single file without dependencies. You can copy it to any machine, container, or whatever, and run it without having to have anything else available, let alone working. For example, I wanted to use it from a USB stick to debug dracut problems on a different machine from the one where I installed it. # ldd /usr/sbin/busybox linux-vdso.so.1 (0x00007ffed915d000) ld-musl-x86_64.so.1 => /lib/ld-musl-x86_64.so.1 (0x00007f1fa63db000) Version-Release number of selected component (if applicable): # busybox BusyBox v1.35.0 (2022-07-20 00:00:00 UTC) multi-call binary. BusyBox is copyrighted by many authors between 1998-2015. Licensed under GPLv2. See source distribution for detailed copyright notices. [... etc ...] How reproducible: Perfectly reproducible Steps to Reproduce: 1. Install busybox from the fedora 37 repos 2. Copy the binary into an environment without musl in /usr/lib. 3. Notice that it doesn't work. Actual results: The busybox binary depends on the musl libc. Installing the busybox package will install musl. Expected results: Whatever other versions there may be, the one called just "busybox" should be a single file with no outside dependencies. Similarly, the "busybox" package itself should have few or no dependencies on any other packages.
