In that it’s not a kernel with just a c library and busybox
This wouldn't be a distro though, at least not in the context of the question being asked by the OP. My point being that Arch isn't "minimalist", because its not really any more minimal than Debian, or Fedora. It is more vanilla than them, preferring to not modify the original sources beyond their packaging, while Debian does do a lot more changes in this regard.
Something like Tinycore, or Puppy are minimalist focusing on running in memory entirely, or Alpine is minimalist by focusing on reducing disk space. Debian, Fedora, or Arch installs, on the other hand, are basically the same in terms of size, unless you also consider them to be minimalist. At which point we are in agreement.
