* Can we upstream some redhat files, i.e. move them out of the
redhat
directory and maintain them in their corresponding code?
Following
files fall in this category:

Anything in the redhat directory could be moved out if it is
going to
be used by another distro. It is there waiting for other distros
to
look at it.

* The ifdown-ib and ifup-ib scripts are redhat-specific. It won't
work
with ifupdown from Debian.

* The files related to mlx4 look like a special handling for mlx4
to me
and they do not following the KISS principle.

One part is managing the need to setup multi-protocol ports on
boot. This seems like a general requirement for mlx4/5 so maybe it
should get some more common solution..

A common solution would be better.

* What's the purpose of the cxgb{3,4} modprobe files?

cxgb is a multi-kernel module driver, those scripts are an attempt to
load the other parts when the main driver is loaded. I'm not sure why
cxgb is special enough to get these files but mlx/etc are not.

I suspect it is old cruft because redhat/rdma.kernel-init handles
things uniformly on systemd environments.

I've been thinking we should patch the kernel to solve this problem
instead of using this ugly userspace solution..

Yes, better fix it in the kernel.

Jarod already created a rdma-core package in debian/control in
commit
8df5873b9. Currently we do not have a rdma-core package in Debian
and
no package with a kernel-boot service file. I know that the openibd
and
 mlnx-ofed-kernel-utils packages shipped a openibd service that
does
similar job.

Yes, pulling something like openibd into rdma-core is the idea here..

Do we want to call the binary package that contains the kernel-boot
service 'rdma-core' or simplify that to 'rdma'? We should use the
same
binary package name across the distributions (unless it's
conflicting
with a naming convention).

I think rdma-core is fine..

Okay. I am fine with this name.

Can you come up with a patch set? I will be happy to review it.
Note
that paths like /usr/libexec/rdma-init-kernel (in rdma.service)
needs
to be made configurable. In Debian, we would install these helper
scripts in /usr/lib/$packagename/$filename.

Maybe Leon's team will try to tackle some of this? It is complicated,
the RH scripts do quite a bit stuff :\

But this doesn't seem particularly urgent for Debian packaging,
right?

I would love to have it in the Debian package. Currently the rdma-core
binary package contains only rdma-ndd. If we defer the kernel-init
part, I have to rename rdma-core or remove it.
