Yes.

I assume you are talking about mapping the nt ACL to unix
Makes sense, group = other. However the way the code is written, it will
interpret the ACL as -abcxyz--- because the Everyone ACL entry is
used up for group. With the change I proposed (I will send a patch), it
would be -abc---xyz, which would in fact be equivalent to -abcxyzxyz, as
Everyone is no more a valid group in the unix sense, so there is nobody
in Everyone !

Yes, for example there is no may to implement chmod abcdefghi if
def != hgi. (mapping unix to nt). What should we do then?

I am curious why it was decided to put the file in the Everyone group.
