Subject: [PATCH] multipath: install all multipath path selector kernel modules

By default, dracut only builds in dm-service-time into the initramfs as

that is the default multipath.conf path selector. If the user changes

the path selector to "round robin" on the fly and runs dracut, multipath

does not find any paths on boot and the user will be dropped into a

shell.

Apparently, in RHEL7 dracut defaults to "hostonly" mode, i.e. modules

not currently in use at the time dracut runs do not get built into

initramfs. This is definitely one case where this doesn't work. A change

to reconfigure multipath probably should not render the system

unbootable.
