Oracle10g CREATE DATABASE creates system tablespace as dictionary managed by default.

Hi All,

   This is more of a comment than a question. Due to somenetwork problems I was unable to use the DBCA, so I was stuck creating a database manually. This is a 10.2.0.3 installation, and I've done it a few times on 8i and 9i, but never before on a 10g. This is the script I used to create the database. The weird thing is that with this script, in which I DO NOT specify locally managed for either system nor sysaux, the RDBMS created the SYSAUX tablespace as LOCALLY MANAGED and the SYSTEM tablespace as DICTIONARY MANAGED. Has anyone ever come across something like this before? I thought that 10g created tablespaces as locally managed by default (and it actually does... except for system aparently)
