The "Setup" page does not allow a link to be created for any system database, including model.
We have many routines in the master database that have been written to be run from within any database and dynamically act on objects within that database's context. For example, we have 500+ databases, many using table partitioning. Several routines generically & dynamically split/merge/truncate/index/rebuild/validate partitions and partition column values for any database.
Like sp_help (which will show object information for the database context from which it is executed), these routines must exist in the master database.
How do we check these routines into Source Control?
