- read rights are not checks in each traversed directory (via sql in a single query to locate the path) - diropen additionally checks for execute rights - fopen checks for read or write depending on the mode - chmod, chgrp, chown methods in sqlfs and egw_vfs/vfs plus an egw_vfs::$is_root var used to grant root rights (no access controll and chown or chgrp without being the owner of a file) - find method (some more params to come) to recursivly search and optionaly execute some callback - egw_vfs::remove doing a "rm -r" / recursive remove or dirs and files - new files or dirs inherit the perms and ownership from the parent directory (no umask) - files/dirs the user has no read rights, in a directory where he has no write rights, get hidden (eg. not showing all the other users / groups home dirs - many new cli commands (chmod, chgrp, chown, find), recursive option for most commands and the ability to use it with root rights, see the usage message if called without options - "cp -r -p" to copy a whole tree incl. ownership and perms, eg. backing up /home to /backup
