Subject: [PATCH 0/4] kmod /usr support
Date: Tue, 11 Jul 2023 17:31:15 +0200 [thread overview]
Message-ID: <20230711153126.28876-1-msuchanek@suse.de> (raw)
Hello,
with these patches it is possible to install kernel modules under an
arbitrary prefix - eg. moving the /lib/modules to /usr/lib/modules with
/usr prefix.
While the modprobe.d and depmod.d search which already includes multiple
paths is expanded to also include $(prefix) the module directory still
supports only one location, only a different one under $(module_prefix).
Having kmod search multiple module locations while only one is supported
now might break some assumption about relative modulke path
corresponding to a specific file, would require more invasive changes to
implement, and is not supportive of the goal of moving the modules away
from /lib.
Both kmod and the kernel need to be patched to make use of this feature.
Patched kernel is backwards compatible with older kmod. Patched kmod
with empty $(module_prefix) is equivalent to unpatched kmod.
Thanks
Michal
