By default rust links dynamically to glibc, while rust stuff is statically linked. Which I think is a reasonably good default. Most Linux systems provide glibc, and you can deploy binaries to them without those systems needing a rust installation. Of course, there's the usual issue with glibc symbol versioning, so you probably want to build your binaries on the oldest supported system (say, a centos 6 container).
