TYPO3 Core

The install tool of recent git master tells me in the "folder structure" check:

/ is not a directory
Path /var/www/hosts/bogo should be a directory, but is of type link

I collect all document roots in one directory so I can utilize virtual mass hosting (automatically makes vhosts available when a directory is available). In this directory, I symlink all vhost directories. This should not be an error.
