[OpenAFS] FC6 / openafs 1.4.2 oddness

[Miles Davis]

(openafs 1.4.2, kernel 2.6.18-1.2798.fc6, dynroot)

Not sure if this is common to all openafs 1.4.2, or fedora core 6, 
since I've only tried it on fc6, but I noticed an odd value for 'df':

Filesystem            Size  Used Avail Use% Mounted on
AFS                   137Y     0  137Y   0% /afs

(I had to look at up -- YB is yottabyte, 2^80 -- I guess I haven't hit 
that storage milemarker yet...)

After years of being used to the fake ~8GB df output, this struck me 
as odd. What defines this fake value?
