 ## Limitations
 
-We have to use the same OS for service containers and for devcontainer, e.g. Debian Buster. This is because different OS may use different system dependencies which highly influence how we build native parts of our dependencies for different services. E.g. Alpine linux uses musl when Debian uses glibc and gem's native extensions compiled in Alpine-based container aren't runnable in Debian container.
