Therefore, in order to get the sticky bit inherited in new
directories, I need to use 'inherit permissions' in samba.
But because of this strange issue I have been discussing with Jeremy,
I cannot get the user/group to be anything other than who you connect
to samba as.
And therefore, ACLs won't help me (I think). There is no ACL I can add
that would restrict write permission if a file already exists, but
allow creation of new files.
That is my current understanding, at least. I will read up on the docs though.
