The 8 bits aren't about indicating that the group encoding is valid;
they're not even encoded. They're about distinguishing PAG's from UID's

i suspect a single bit would be sufficient to distingush between pag's
and uid's? it does appear to be encoded in the pag and is used as
some sort of check to see if the value derived from the groups is a
pag. perhaps i dont understand afs_get_pag_from_groups().
Ugh; you're right. I'd forgotten about the bizarre divide-by-three
encoding for the top four bits, which are always constant anyway.
well i guess the range would just grow.
I get the impression people might not like that.
Now, it doesn't bother me; our UID's are capped at 16K until we work out
some namespace allocation issues, and we're not in danger of exceeding that
soon. But other people might feel differently.
