For some use cases, a monolithic kernel-modules package containing
all modules built from the kernel sources may be preferred.
For one, download time is shorter and installation time is faster.
There's still an outstanding issue though. Unless you generate the
provides/rdepends along with the monolithic package, any existing
rdepends on kernel modules break.
The next patch in the thread does it.
While that likely isn't something you hit in your use case, it would
be something that would have to be covered to make this part of core.
About 7 years ago, I was most of the way through a similar change,
that created on large package with all the rprovides generated (I'm
not sure I can track it down now, but I could have a look), since
doing an on target update with thousands of kernel module package is
very painful.
Well, yes. In our defconfig, about 1500 kernel-module-* subpackages
were created and had to be upgraded at once. It was *very* painful
with over 50 minutes to download and upgrade the kernel.
Cheers,
Bruce
Set KERNEL_SPLIT_MODULES="0" for this.
The default is one subpackage per module.
