 257 <h1>Welcome to GLCAS</h1>
 258 Welcome to GLCAS, I cant find my configuration file so im assuming you installing me for the first time<br>
 259 If this is not correct then we have a big problem that needs to be solved, i hope you have a backup of the old
 260 config, cause that will make life easier.<br><br>
 261 However, if this is the first time you have run this app, then all is good with the world. All I need right
 262 now is a place where i can store my config. I search the following directories for the location of my
 263 configuration (webconfig)<br>
 264 <li> /var/run/glcas/
 265 <li> /var/lib/glcas/
 266 <li> <?php echo $underroot?>/var/glcas/
 267 <br><br>
 268
 269 As root, you must now create one of these directories and change the ownership of the directory to the web owner.
 270 (chown <?php echo $uid?>:<?php echo $gid ?> the_path_you_choose).<br>
 271
 272 Now, tell me where you want me to create the webconfig file:<br>
 273 <form method="post">
 274 <select name="installdir">
 275 <option value="/var/run/glcas">/var/run/glcas</option>
 276 <option value="/var/lib/glcas">/var/lib/glcas</option>
 277 <option value="<?php echo $underroot?>/var/glcas/"><?php echo $underroot?>/var/glcas/</option>
 278 </select>
 279 <input type="submit" name="Go" value="Go">
