    QEMU labs: temporarily restore the use of the ifconfig command
    
    - In /etc/qemu-myifup:
      Works: exec /sbin/ifconfig $1 192.168.100.1
      Doesn't work: exec /sbin/ip a add 192.168.100.1/24 dev $1
      ... though these commands seem equivalent
    
      Will investigate later

 To load a kernel in the next lab, we will setup networking between the QEMU emulated
 machine and the host.
 
-The first thing to do is to create a \code{/etc/qemu-myifup} (for example)
-script that will bring up a network interface between QEMU and the host. Here are its contents:

 Of course, make this script executable:
