The distribution you install is just a collection of the exact binaries
you would get in a normal install. Therefore it is the distribution
itself which has a libc, and whether that is glibc, musl, or dietlibc
(just to name an utterly outlandish option) is up to the distribution.
However, there is one additional file installed, called /init, which is
also the root of the emulated process tree. And that file is statically
linked against musl (as you can tell by running "strings" on it). It
apparently generates a couple of files from Windows' current system
settings (like /etc/resolv.conf).

Ciao,
Markus
