stock core 2 kernel possible bug within depmod command??

[David Kramer]

I looked all over the web but couldnt seem to find anything about a bug
within depmod on the core 2 test stock kernel(2.6.3-2.1.253.2.1).  When I
run depmod I get a permission denied error like this:

FATAL: Could not rename /lib/modules/2.6.3-2.1.253.2.1/modules.dep.temp
into /lib/modules/2.6.3-2.1.253.2.1/modules.dep: Permission denied

I can copy the modprobe.dep.temp file manually from within the kernel, but
this seems like a bug since the make install is runu by root and both. 
any thoughts on how to clean this up?

Thanks,

DK
