6.4. Implementation

6.4.1. System Startup

Boot the PC using the floppy labeled "boot disk". Place the recently created root disk in fd0 when prompted. The output should resemble the example below:

GNU GRUB version 0.95 Uncompressing Linux... Ok, booting kernel. .. .. [various kernel messages] .. VFS: Insert root floppy to be loaded into RAM disk and press ENTER RAMDISK: Compressed image found at block 0 VFS: Mounted root (ext2 filesystem) readonly. Freeing unused kernel memory: 178k freed Checking local filesystem integrity. /dev/ram0: clean 105/1024 files 2842/4096 blocks Remounting / as read-write. Mounting local filesystems. Setting the hostname. INIT: Entering runlevel: 1 # _

6.4.2. Verify success of startup scripts

Use the mount command to check that local filesystems are mounted as read-write. The output should look like the example below.

bash# mount /dev/root on / type ext2 (rw) proc on /proc type proc (rw)

Check the hostname.

bash# uname -n gnu-linux

6.4.3. System shutdown

Bring the system down gracefully with the shutdown command.

bash# shutdown -h now

We should see the following output from init and the shutdown scripts:

INIT: Switching to runlevel: 0 INIT: Sending processes the TERM signal Terminated INIT: Sending processes the KILL signal Unmounting local filesystems. Initiating system halt. System halted.
