I think we have almost no special handling for symlinks in monotone at all. And 
while this mostly works as it should (for example when you work on a symlinked 
database where we give the symlink to sqlite and this does the actual work), it 
breaks for use cases like the one above.

Now we could add another requirement "all symlinks resolved" to our "normalized 
paths" definition in src:address@hidden:monotone-0.99#99, but I doubt this is 
either an easy task (handling symlink loops) nor something which comes without 
cost (slower path handling and / or unwanted or unexpected behaviour). This 
doesn't say we shouldn't do it, but I'd strongly vote to do this after 1.0 and 
rather point the user to list the new database location as additional location 
via the get_default_database_locations lua hook.

I forgot to mention I had done this as well:

    cd ~/tmp/foo
    mtn register

The problem is, of course, that monotone tries to check if the database pointed 
at in the workspace is the same as the one being listed, doesn't resolve 
symlinks before the comparison, so the registered workspace doesn't seem to be 
the one connected to that database after all, and is therefore not displayed or 
counted.

Steps to reproduce the problem:
-------------------------------

1. move a database from previous repository place to the default database 
directory, but make sure to not break existing workspaces:
    mv ~/monotone-repos/foo.mtn ~/.monotone/databases/
    ln -s ~/.monotone/databases/foo.mtn ~/monotone-repos/
2. list available databases:
    mtn list databases

Expected result:
----------------

:foo.mtn (in /home/levitte/.monotone/databases):
        se.lp.foo (in /home/levitte/tmp/foo)

Actual results:
---------------

:foo.mtn (in /home/levitte/.monotone/databases):
        no known valid workspaces

Output of `mtn version --full`:
-------------------------------
