Dracut is the only tool to create initramfs on many distros and it works fine
with multipath so far. Dracut is to initramfs-tools what systemd is to basic
initscripts.
Dracut is modular and event driven while initramfs-tools is monolithic and
linear static.
If you look at /usr/lib/dracut/modules.d you'll notice that a module already
exists for multipathd. (/usr/lib/dracut/modules.d/90multipath and
/usr/lib/dracut/modules.d/90multipath-hostonly)
man dracut
man dracut.modules
man dracut.cmdline
See also the module-setup.sh in both 90multipath and 90multipath-hostonly
modules
Dracut is really a wonderful piece of code that is really easy to understand
and that can create really powerful ramfs images.

The problem is that nobody, afaik, has tested the combination of
multipath-tools and dracut together. dracut, afair, claims to be a
drop-in replacement for initramfs-tools. But I am not sure at all.
Right now, multipath-tools has tight integration with initramfs-tools.
Also the sg3-utils-udev package ships in modules to add further
integration.
If dracut can do the equivalent, then we can relax the dependencies.
