I understand, I don't want to break things for sure.
In the meantime, I think that dracut native multipath module has the logic to
handle stackable storage, though, of course, on Debian nobody can test as both
dracut and multiupath-tools can't be installed together for further testing
debugging.
On my side, (Systemimager), I made multipath-tools optional (dracut generates a
warning telling it can't load the multipath module because multipathd binary is
not found), and that's ok for those who don't need multipath)
It's up to you to decide what is the best for Debian.
My though (outside this bug reporting) is that it would be a good step forward
for Debian to switch from old initramfs-tools to modern dracut.
Cheers,

Hi Olivier,
I am not denying any of what you have said below. Dracut may be a great
tool. But unfortunately, it does not have the uptake in Debian, that
initramfs-tools has. Just look at the popcon stats.
multipath-tools needs tight integration with the plumbing layer to
ensure you have a stackable storage. For Debian, the work so far has
been done integrating it with initramfs-tools.
I am not opposed to adding dracut as an option. It is just that I have
never worked on it. Nor have any users/developers ever reported about
its integration here.
If dracut can serve as a drop-in replacement, I don't have any problem
adding it as an OR dependency in `sg3-utils-udev` package.
