I know TYPO3 runs under ISPCONFIG. Problem/Question ist following situation On my old SuSe server I run several TYPO3 sites from the same TYPO3 source. Following strcture /srv/www/htdocs/vhosts/typo3source /srv/www/htdocs/vhosts/site_1 .... /srv/www/htdocs/vhosts/site_n Site 1 to n are symlinked for TYPO3 to...vhosts/typo3source So to upgrade all sites I just nee to change typo3source. htdocs and all subdir have wwwrun:www as owner Cant' see to to something similar with the trustee structure of ISPCONFIG. May be I am blind. Need some idea to realize a similar structure as above. On the other way on TYPO3 source for more websites ist space efficient. Thanks for help Rainer
