Hello, depmod uses readdir to traverse /lib/modules/`uname -r`/, but readdir sorts files by d_off. It means that if I create two links with the same name in the weak-updates directory, for example: weak-updates/opt/kernel1/extra/a.ko ->/ opt/kernel1/extra/a.ko weak-updates/opt/kernel2/extra/a.ko ->/ opt/kernel2/extra/a.ko
what are these kernel1 and kernel2? depmod respects the priority configured in depmod.d for searching, but here it seems you have only weak-updates configured in your depmod.d so both of them have the same priority. Looks rather like you want this in your config rather than using symlinks: external * /opt/kernel1/extra /opt/kernel2/extra but I don't know what kernel1 and kernel2 are in your setup.

Even with the same kernel, the same module may generate different modules.dep on different machines, and it is impossible to predict which ko will be used Maybe we can cache the directory name first and sort it? If can develop in this direction, I will try to make a patch Best Regards, Yang Yanchao
