Hmm, after this, I left things as the were (nfsd module loaded, but a 0
use count )
I got a BUG while updatedb was running,
(I tried this on a debian machine/kernel)
Same bug on :
cat /proc/self/mounts
I'll take a look at this issue later, after my vacations, unless someone
wants to take a look before me ;)
