The default MODLIB value is composed of three variables

MODLIB = $(INSTALL_MOD_PATH)$(KERNEL_MODULE_DIRECTORY)/$(KERNELRELEASE)

However, the kernel.spec hadcodes the default value of
$(KERNEL_MODULE_DIRECTORY), and changed value is not reflected when
building the package.

Pass KERNEL_MODULE_DIRECTORY to kernel.spec to fix this problem.

Build on top of the previous patch adding KERNEL_MODULE_DIRECTORY

The SRPM package created by 'make srcrpm-pkg' may not work
if rpmbuild is executed in a different machine.

That's why there is an option to override KERNEL_MODULE_DIRECTORY?

Yes.
But, as I pointed out in 1/2, depmod must follow the packager's decision.

'make srcrpm-pkg' creates a SRPM on machine A.
'rpmbuild' builds it into binary RPMs on machine B.

If A and B disagree about kmod.pc, depmod will fail
because there is no code to force the decision made
on machine A.

Thanks

Michal

%{make} %{makeflags} INSTALL_MOD_PATH=%{buildroot}
KERNEL_MODULE_DIRECTORY=%{KERNEL_MODULE_DIRECTORY} modules_install


will align with the specified install destination,
but depmod will still fail.
(same issue as 1/2)
