So VyOS is heavily dependant on this one, no need to remove.
This is not just wrong, but, as anyone who tried to go beyond the native CLI on EdgeOS can attest, almost slanderous. ;)
VyOS uses real coreutils (ip-utils-ng etc.) for those ones. Some VyOS packages list busybox but I believe it's a legacy. The only thing that probably truly depends on it is initramfs-tools, but with image upgrades, I think having initramfs-tools in VyOS is an artifact that is not needed.
