How to configure dovecot to use different default mail_location for
system (uid<1_000) and normal users (uid>=1_000)?

I want to to use by default
* classic mailbox in standard location for system users
* maildir in $HOME subdirectory for normal users

That depends :-)

If you have just one userdb, configure the default mail_location for
most users and return a mail extra field for the other ones.

You use passwd? This probably will not work, see
http://wiki2.dovecot.org/UserDatabase/ExtraFields about the syntax

You could probably copy the set of users, that requires extra fields,
from your /etc/passwd to somewhere else, adding the extra field. Then
configure the copy as userdb { driver passwd-file } _before_ the userdb
{ passwd }. That way, the entries in the passwd-file override the ones
in /etc/passwd, because they are found first.

I have used userdb/passwd fix for a system with a few "real user
mailboxes". I wanted something better fit for larger systems.

Hmm? You need to return a different mail field for one set of users. /etc/passwd cannot do this. So you need some other userdb for the set of users, for whom you want to override the default mail_location, be it passwd-file, SQL, LDAP, ... .

You wrote "normal users (uid>=1_000)", so they are system users in /etc/passwd as well, I assumed. If those system already use another user database, try using it and extend it with the Dovecot settings.
