Every place where the paths for mdadm or mdmon is explicit,
it should use the BINDIR setting, not "/sbin/".

1/ Add systemd shutdown script to ensure DDF and IMSM are
clean before we actually shutdown
2/ Get udev to tell systemd to run the mdmon@mdXXX.service
units when a member array appears.
If we boot off a member array (with dracut at least),
the mdmon started in the initramfs will lose track of
/sys etc, so we need to restart it.
systemd will try to forget about it too (but not actually
kill it because we said not to do this).
Having udev tell it to start it will allow a new mdmon to
run which can see /sys, and systemd will know about it.
3/ Always use --offroot and --takeover when starting mdmon with
systemd
--offroot is needed else shutdown will hang.
--takeover is needed incase an mdmon was started earlier
(e.g. in initramfs).
Neither hurt if they aren't actually needed.

This systemd unit file runs mdadm in --monitor mode.
It is started by a SYSTEMD_WANTS signal from udev whenever
an md array is started that would benefit from mdadm --monitor.
Commandline arguments can be provided by a script
/usr/lib/systemd/scripts/mdadm_env.sh
which should write an
MDADM_MONITOR_ARGS=....
line to /run/sysconfig/mdadm
A script to extra args from SUSE's /etc/sysconfig/mdadm file
is provided.
If no mdadm_env.sh is provided, then args are "--scan" which
requires "mail" or "program" to be set in /etc/mdadm.conf.
I believe this is suitable for Fedora.

Right now, the rules that run blkid on raid arrays are executed after
the assembly rules. This means incremental assembly will always fail
when raid arrays are again physical components of raid arrays.
Instead of simply reversing the order, split the rules up into two files,
one dealing with array properties and one dealing with assembly.
