TYPO3 Core

• Use a clean TYPO3-installation with an empty page-tree.
• In installer use upgrade-wizard to check for errors. It will suggest to automatically create a page "Home" for you with a root-template. Details for this step show:

Integrate TypoScript Root Template
INSERT INTO pages (pid,title,is_siteroot,crdate,tstamp) VALUES ('0','Home','1','1393669356','1393669356')
INSERT INTO sys_template (pid,title,root,clear,crdate,tstamp) VALUES ('1','Default Root Template','1','1','1393669356','1393669356')

Note that "is_siteroot" is set correctly. However the pagetree only shows a regular page-icon, not the siteroot-icon. Editing the page-properties and just saving it (is_siteroot is already checked!) and reloading the pagetree makes the correct icon appear.
