Why is the default Ubuntu boot partition so small? How can I increase it? : <p>Recently I created a Ubuntu server. During install I accepted the default options. Installer creates a 236M <code>/boot</code> partition as shown below. After only a few months the partition is full. Is this partition not awfully small? How can I increase it?</p>
