To be precise, it's not anaconda but "loader", the C program that starts
anaconda and cleans up after it. It looks exactly for "mdmon". See
https://git.fedorahosted.org/cgit/anaconda.git/tree/loader/shutdown.c?h=rhel6-branch#n59

Sorry for having explained unclearly. This is *not* a systemd
environment. There is no regular "init" process running AFAICT, "loader"
takes that role as far as necessary in the installation environment.

If this isn't applied, in the RHEL/CentOS 6 installation environment,
"loader" will kill mdmon, and a subsequent "mdadm --wait-clean" will
hang forever.
