With the recent port of the build system to Meson, it is now built together with the tools though. The Kata Containers [1] project build QEMU with --disable-tools to decrease the attack surface, apart from the fact that tools (except for virtiofsd) aren't used at all. So the ability to build only virtiofsd is appreciated. On commit cece116c939 it was introduced the --enable-virtiofsd option. One might think that option will enable the virtiofsd build regardless of --disable-tools but it isn't the current behavior. So the patch that I am sending allows to disable all tools but virtiofsd. Side note: in a private chat with Stefan Hajnoczi he come up with the idea that perhaps --disable-tools could be like --without-default-features where one can add back on feature-by-feature basis. This is outside the scope of this series but I thought in sharing because IMHO it is deserves a discussion.
