caveat, I am not into PAS yet, I am only following the discussion for 
fuutre work, so I may not be understanding corretly how PAS works:

"first found above" sounds like it is the Zope-root in a normal Plone 
install: ie. / is the zope root, where there is an acl_users. /Portal is 
the Plone default install. /Portal/acl_users is the non-pas location of 
a user folder if one creates one at or after creating a Plone Site object.

"first found above" means... /Portal/../acl_users --> /acl_users?

Or does "first found above" mean /Portal/acl_users ?

Assuming, I have understood this correclty, if there is no 
/Portal/acl_users, then I can understand that there logically is no 
other user folder than /acl_users to PAS-ify... but that  is, imho, 
perhaps a bit too invasive - better to offer the user an option to 
create a new PAS-ified acl_users at /Portal level rather than silenlty 
PAS-ify the root acl_users.

We have all learned that replacing the root acl_users is generally not a 
good idea, so doing this semi-silently is perhaps a bit premature. Until 
Zope ships with PAS as the default user folder implementation, replacing 
root user folders should be treated as a special case that is to be 
avoided and alternative options should be offered.

Apologies if I am misunderstanding everything and wasting bandwith.

Sincerely,
