The addition of kernel-modules is going to greatly increase the

this one in only intel-quark.
On the other hand, then lot of hardware won't work, because drivers
are
built as modules... Pretty much only boot-critical drivers should be
built into the kernel. I find it especially strange if we have
linux-firmware installed but not modules, because most of the
firmwares
are used by modules (WiFi drivers, etc). So if kernel-modules is
removed
then also linux-firmware should be removed, that is another large
package and not boot-critical.
This package is about 900K
linux-firmware PKGSIZE according to pkgdata is ~86M.
IMO, there are better places to shave off size of minimal images
than
cutting out hardware support.
You realize that core-image-minimal goes from 8.7M -> 59M by adding the
modules, so there is not other place to shave off size in the minimal
image.
MACHINE_EXTRA_RRECOMMENDS does not affect core-image-minimal
(MACHINE_ESSENTIAL_* do).
40M is in /lib
6.8M in /boot
I think this is a case where the RefKit includes modules but it does
not go into meta-intel, this is more of a Distro/Image level choice
than a BSP level choice. So this is not a customer BSP in refkit.
The patch tries to make MACHINE_EXTRA_RRECOMMENDS setting more consistent
accross intel-* machines. Jussi has a good point that linux-firmware
without kernel-modules
is pointless.
IMO, the config choice is whether to install MACHINE_EXTRA_RRECOMMENDS
or not.
