Part A - Configure a GRUB boot menu
===================================

Work in Part A is based on Worksheet 13.

1. Create the following GRUB configuration.  In each boot menu entry,
   insert the given words at the start of the title for that boot menu
   entry, as you did in the worksheet.

   a) Take a snapshot and save your current GRUB configuration file.
   b) Have GRUB ask for a password (unencrypted): MyGrub
   c) Have GRUB time out after 30 seconds.
   d) Have GRUB choose the third (last) default boot menu entry.
   e) The title of the first boot menu entry must start with: normal
      - this first boot menu entry does the usual boot
   f) The title of the second boot menu entry must start with: single user
      - this second boot menu entry boots in single-user mode
   g) The title of the third boot menu entry must start with: text only
      - this third boot menu entry boots in text-only mode
      - this will be the default boot menu entry GRUB chooses

Check your work using the assignment13check program.

Part B - Configuring Run Levels
===============================

Work in Part B is based on the Class Notes and man pages.

1. Save a listing of all services and all run levels.

2. Disable (turn off) the Bluetooth service in all run levels.

3. Completely remove the "smolt" service from chkconfig management.

4. Enable the Apache HTTP Server service only in run level 5.

5. Save a second listing of all services and all run levels and
   compare that second listing file with the first listing file.
   Three lines should have changed.

6. Start the Apache HTTP Server using either its start-up script or the
   corresponding "service" command (RTFM).  Confirm that it is
   running by using the Firefox web browser inside Fedora 12.

Check your work using the assignment13check program.

Part C - Process Listing
========================

1. Place a full list of all processes, all users, long format, full
   wide listing, into file assignment13ps.txt in your HOME directory.
   It should be "approximately" 150 lines and 14KB.

1. Download the assignment13check program to Fedora 12.
   (Instructions for downloading were given in previous labs.)

2. Run the assignment13check program as many times as you like.
   (Instructions for running checking programs were given in previous labs.)

3. Rename the assignment13marks.txt file to be assignment13.txt
