Understanding configuration profiles
Is tying disk images(with a OS) to a configuration profile equivalent to having one machine(server)? Does that mean if I get an extra IP, i can have 2 machines? (one IP per configuration profile)
I am suspecting that "1 linode = 1 machine". If so, what is the advantage of having multiple configuration profiles and multiple IPs in 1 machine? Thank you.

If you create multiple configs, it doesn't matter, because only one can be booted at a time per linode.
The idea behind multiple configs would be if you want to test a kernel before rolling into production.

The most common reason for having multiple IPs on one machine is to run multiple SSL/TLS web servers - you can only have one https server per IP.
@mwalling:
Config profiles are like entries in your grub/lilo menu: Different ways to boot your machine (kernels, root partitions, run levels, etc).
This is probably the best way to explain it I've heard yet.

I have been going through your docs and I am trying to understand the concept of configuration profiles in the Linode manager.
As mwalling said, think of them as different systems. Most of the Linodes I administer have two configuration profiles – production and recovery; in this case, the disks attached are the same, and the difference lies in the kernel, initrd, and one disk image (all configured for Finnix).
