root on multipath and dracut

root on multipath and dracut

[Hannes Reinecke]

Hi Ben,

as we're switching to dracut/systemd nowadays I've tried to setup
and enable root on multipath for this, too.

As you might've seen, I've already added proper systemd support for
multipath-tools, so it should be easy to plug it into dracut.

Or so I thought.

As it turns out, dracut is trying to add some RH-specific rules files:

40-multipath.rules
62-multipath.rules
65-multipath.rules

which have only _very_ sparse documentation.
Wouldn't it be a good idea to settle on a default set on scripts
here and include those into the multipath-tools repository?

Cheers,

Hannes

Currently we only ship /lib/udev/rules.d/62-multipath.rules with
device-mapper-multipath-0.4.9-56.

Gentoo was using 65-multipath.rules and we formerly used 40-multipath.rules.

So, basically dracut tries to find any of them to be backwards compatible and
cross distro.
