Here is a fix for you to try...
grab /opt/sark/generator/tftpSQL.php using your favourite editor.
At or around line 110 find
$row['provision'] = preg_replace ( ' /\["(.*)"/ ',"", $row['provision'] );
replace it with
$row['provision'] = preg_replace ( ' /\["(.*)"\n/ ',"", $row['provision'] );
Save it back, issue a commit and then let me know if it worked for you.
Kind Regards
S
