Das ist i.d.t. etwas ungewöhnlich, lässt sich aber recht einfach einstellen.
aus der config_default.php (incl. eventuell anderer interressanter werte)
Code:
00106 'BE' => Array( // Backend Configuration.
00107 'unzip_path' => '', // Path to "unzip".
00108 'diff_path' => 'diff', // Path to "diff". For Windows this program can be downloaded here: http://unxutils.sourceforge.net/
00109 'fileadminDir' => 'fileadmin/', // Path to the fileadmin dir. This is relative to PATH_site. (Automatically mounted for admin-users if set)
00110 'RTEenabled' => 1, // Boolean. If set, the Rich Text editor will be an option in the backend. Notice that the editor must be enabled per-user and options are configurable. See admin guide.
00111 'RTE_imageStorageDir' => 'uploads/', // Default storage directory for Rich Text Editor files
00112 'RTE_reg' => array(), // Contains arrays of possible RTEs available (keys=extKey, values=cfg-array). Each array contains a key, "objRef", which contains a user function call with prefixed script path and instanciating a persistent global object. This can report back if browser requirements are OK, draw the RTE and do the transformations needed.
00113 'staticFileEditPath' => 'fileadmin/static/', // Path to directory with static files for editing (see table sys_staticfiles_edit). Relative to PATH_site.
00114 'lockRootPath' => '', // This path is used to evaluate if paths outside of PATH_site should be allowed. Ending slash required! This path is also used to restrict userHomePath/groupHomePath. Observe that the first part of 'userHomePath' and 'groupHomePath' must be the value of 'lockRootPath'. Eg. '/home/typo3/'.
00115 'userHomePath' => '', // Path to the directory where TYPO3 backend-users have their home-dirs. Eg. '/home/typo3/users/'. A home for backend user 2 would be: '/home/typo3/users/2/'. Ending slash required!
00116 'groupHomePath' => '', // Path to the directory where TYPO3 backend-groups have their home-dirs. Remember that the first part of this path must be 'lockRootPath'. Eg. '/home/typo3/groups/'. A home for backend group 1 would be: '/home/typo3/groups/1/'. Ending slash required!
00117 'userUploadDir' => '', // Suffix to the user home dir which is what gets mounted in TYPO3. Eg. if the user dir is "../123_user/" and this value is "/upload" then "../123_user/upload" gets mounted.
00118 'fileCreateMask' => '0644', // File mode mask for Unix file systems (when files are uploaded/created).
00119 'folderCreateMask' => '0755', // As above, but for folders.
es ist somit über das installtool als auch per var setting in der localconf.php abgreifbar.
