/root/.debug/ ... ?

[Shraddha Kamat]

Might be a silly question - but since I am a newbie I am trying to
understand the reason for existance for most of the stuff that I find
while reading the code --- here is my question -- 

I see that there is a directory - /root/.debug/lib/modules/3.8.0-rc5
+/kernel/net/8021q/8021q.ko/8a73921f509a12a1cd7fb49dd8d1203197294c9e
Why is this directory here for ?  

What is this file 8a73921f509a12a1cd7fb49dd8d1203197294c9e ?
