require AMD64, including current Apple hardware. If you are not certain
which you need, use this one. It works on either 32-bit or 64-bit systems,
so it is the default choice.
AMD64: If you know you are using a processor based on the AMD64 or
EM64T architecture (for example, Athlon64, Opteron, EM64T Xeon,
Core2), you should choose this version because it will be a bit more
efficient on your hardware. This is the one on the attached DVD.Planning Partition Strategies
Partitioning is a topic that can make novice Linux users nervous. Coming
from a Microsoft world, where you might be used to having just one hard
drive, it can seem a bit strange to use an operating system that makes
partitioning a hard drive possible or even preferable and common.
Depending on your needs, you can opt to have a single large partition to
contain everything, which is the official recommendation of the Ubuntu
community and developers. You might prefer to segment your installation
across several partitions if you have advanced knowledge and specific needs.
If you are installing Ubuntu in a corporate or business environment, the needs
of the business should be a primary concern. Be careful to ensure that you
build in an adequate upgrade path that allows you to extend the life of the
system and add any additional storage or memory.
Knowing how software is placed on your hard drive for Linux involves
knowing how Ubuntu organizes its file system. This knowledge helps you
make the most of hard drive space. In some instances, such as when you’re
planning to have user directories mounted via NFS or other means, this
information can help head off data loss, increase security, and accommodate
future needs. Create a great system, and you’ll be the hero of information
services. The Linux file system is covered along with commands to
manipulate files and directories in Chapter 10, “Command-Line Beginner’s
Class.”
To plan the best partitioning scheme, research and know the answers to these
questions:
How much disk space does your system require?
Do you expect your disk space needs to grow significantly in the future?
Will the system boot only Ubuntu, or do you need a dual-boot system?
How much data requires backup, and what backup system will work
