master starts first, id is 1
tempdb is usually just before model, especially evident like Gail said if tempdb is not present as it copies tempdb from model, something which it cannot do if the files are already open.
MSDB is last
Interesting... how is model used when creating a new database then?
Ever tried viewing model or its properties while a database is being created.
No. What happens?
usually an error failing to lock the database
