[lustre-discuss] Building against kmod spl/zfs

I think I figured it out. I have to use DKMS on the system I am using to build the RPMs, but I can use the kmod rpms that were produced on the systems that I am running lustre on.
Doing it that way seems to work for me.

do you use rpm based system or something else?
I do not use yet kmod zfs lustre (using dkms) but I use kmod zfs on other zfs appliance.
I case of rpm base system you need to install zfs-release-1-5 rpm to configure yum.
Yum may use prebuilt dkms modules. RHEL based systems have kABI compatibility so you do not need to rebuild zfs for each minor kernel update.
Yum needs proper repository enabled when installing rpms (zfs-kmod vs zfs for dkms or kmod). Sources are at zfs-source.
So you may install zfs from zfs-kmod repo and sources from zfs-source. Then build lustre against zfs-source headers.
a full example has been given recently: http://lists.lustre.org/pipermail/lustre-discuss-lustre.org/2017-January/014139.html

I am starting to try and build lustre using just kmod instead of dkms. Now the trouble I am seeing right off is that lustre wants the spl and zfs source (which is part of the dkms packages) just to configure it. So what would be the appropriate way to try and make kmod-lustre? Should we obtain the spl source and just point to it? Or perhaps there is no kmod for lustre server as yet?
My simple config line is:
./configure --enable-server --disable-ldiskfs --with-linux=/usr/src/kernels/$(uname -r)
