No source removal if no modules

[sveyret]

Hi,
If I understand the source code correctly, the kernel source directory (/usr/src/linux-xxx) is tied to the module directory (/lib/modules/xxx) because it is read from a link (named build).
On one of my server, I have a kernel where CONFIG_MODULES is disabled. In this case, there is no modules directory and so, eclean-kernel is never removing my old sources.
Is there currently a way to say to eclean-kernel to remove the source directories without looking for the modules? Or could that be an option?
Thank you.

No, there's no such option. Source directories are largely unpredictable, so we rely on these symlinks to tell us which one is correct.

With newer kernels make module_install works even with CONFIG_MODULES not set.
I do not know who sets up the symlinks, but if one is using gentoo-kernel to manage kernels, this issue does not exist since gentoo/gentoo#32358
