Look a little closer at that message -- the file node0/cpumap *is*
there, but tar is getting weird data from it (it expects 4096 bytes
but only gets 3). Here's the output I had later in my mail:
>> /sys/devices/system/node/node0 % cat cpumap
>> ff
It corresponds to the 3 bytes that tar assumedly was able to get (2
f's + \n).
So I'm not sure that tar'ing up these directories will work as
expected -- even with a kernel that provides all the information that
we're looking for.

Right; I just do it out of habit to ensure to grab everything. :-)
