bsdlabel wierd.

Hi

I was experimenting with growfs yesterday and I noticed this wierd
thing crop up in my label.  Notice the 'a' partition which I can
no longer get rid of and appears automatically.  using bsdlabel -e
I have to delete this partition if I want to change any of the other
partitions (it complains about overlapping partitions otherwise).

[brane-dead] / # bsdlabel /dev/ad0s1
# /dev/ad0s1:
8 partitions:
#        size   offset    fstype   [fsize bsize bps/cpg]
  a: 20044064       16    unused        0     0       
  c: 20044080        0    unused     1024  8192         # "raw" part, don't edit
  e: 20044080        0    4.2BSD     1024  8192 46248 

What am I missing?  BTW, growfs barfed too with a 'rdfs: read error'.
