This video covers two topics: seeds and architectures. Seeds are the essence of automated installations. An automated installation can help administrators work with large numbers of Linux systems. One Ubuntu method, at least the one cited in the UCP curriculum is Preseed, thus the term seeds. An automated installation file is in essence an answerous file, when loaded during the installation process, it answers the questions that would otherwise have to be answered with manual input. Like other Linux configuration files, Preseed files are text files. To see the structure of a typical Preseed configuration file, review the Preseed sub directory on any Ubuntu Linux CD/DVD drive. I've loaded it up on my media CD-Rom directory and I see several Preseed files in there. Let's take a look at one. And another, see how few lines there are in a Preseed file? Well those lines are instructions to the installation program. And since there are very few lines there, most standard installations require a lot of input from the administrator, but to review a more extensive Preseed file, find the example Ðpreseed.text.gz file available on the CD/DVD drive in the doc/install/manual sub directory. There it is, you can now compress that file, or you can just use the List command. You have to remember to cite the file. And there it is, you can review the file on your own. As you won't see an Ubuntu installation during the UCP exam, that's as much as you need to know. However, if Ubuntu ever develops a certified engineer exam, and I expect they will, an exam to rival the Red Hat certified engineer exam, I fully expect a detailed understanding of the example Preseed configuration file to be part of that exam. Now, to the next sub-topic, architectures. Ubuntu has a pretty simple official support for architectures. Official Ubuntu releases are available for 32 and 64-bit Intel incompatible CPUs. It's simpler than it was before. Ubuntu server was supported on the Sun SPARC CPU architecture through the Gutsy Gibbon release. Ubuntu no longer supports that architecture, at least not officially. This has simplified the Ubuntu process, especially when contrasted to Debian's. Debian Linux, the developers behind that distribution, they have to deal with over a dozen architectures. But ports are available, Mark Shuttleworth suggests that every Ubuntu developer is also a Debian developer. In that mold, Ubuntu ports are available for a number of other architectures that in other words, they've been recompiled for those architectures. At this time, ports are available for based on the CPUs based on PowerPC, the HP Risk, the Itanium 64, and the Sun SPARC architectures.
