cn=config and mdb questions

[Da Rock <openldap-technical@herveybayaustralia.com.au>]

Aside from other issues (which haven't really been solved... just 
possibly worked around :/), I've been doing some tinkering and have 
raised some questions which I'm hoping will have answers to.
1. cn=config and friends: Looking at the schema and methods used to 
implement this config type, I got to considering that I could (in 
theory) name my databases such as olcDatabase=MyLDAPDatabase (or the 
like), rather than bdb/hdb/mdb. I then found that I couldn't and then 
looked it up to see why - I found that it had a naming restriction, but 
not why. Aside from possible limits within the programming as it stands 
now, is there some semantical issue why this is the case? Wouldn't 
possibly be easier to determine which database is which if the 
administrator was able to name them as they wish?
2. mdb: I know this is the way we're expected to go with ldap now, but 
what is the point of a db that can't grow as needed? It seems rather 
limiting (and old school - remember early unix programming on the old 
IBM mainframes and DOS for the PC's later with the 640k limit), so why 
the push in this direction? Or is it expected that this will be resolved 
in the future?
Cheers
