From: Zhixiong Chi <[email protected]> When user execute the command "rpm -qai --root=$dir",if $dir doesn't exist or is unwritable as result of making a typo in rootpath,then it will create dirent $dir and subdirectory. So we should add the check function to fix it before creating relational subdirectory,and warn the incorrect rootpath to user. It just checks the rootpath reasonableness when the user input the argument(--root=/-r=).
