I've only checked twice, but the output is identical, so they appear to 
be consistent.  What seems interesting about this to me is that while 
most of them are in the same directory, about 1/4 are just scattered 
around the FS.  None of it is anything critical though, and the system 
runs just fine (or at least, it appears to, most of the issues I'm 
having appear to be GPU related, and don't seem to have anything to do 
with BTRFS).
