I cannot find a way to create sections in a site, like this one: groups.drupal.org.
This is not site aliasing like pulling up a home page from different aliases, that is an option in hostmaster.
Thank you.

Since nobody responded so
Since nobody responded so far, I will try to contribute something.
First you need to set an A record for section in your DNS manager.
Like so: section.domain.org, then create a subdomain in your Aegir instance for testing purposes.
When done testing migrate that mini site to same platform as main site.
You should link both sites together, like link <- back to Drupal.org.
If something I said is wrong or needs improvement, please add comment.
I don't understand what
I don't understand what exactly you're trying to accomplish. The usual meaning of a "section" is, well, a section of one website. Like example.com/section1, example.com/section2, etc. Depending on other requirements (different styling) etc. it could be as simple as using categories.
But it looks like you want subdomains? Take a look at https://drupal.org/project/domain module if you want to use multiple (sub)domains for one website.
Thanks for answer. Please
Thanks for answer.
Please post a link to "categories", is that a module?
Regarding the domain module, is that what Drupal uses for groups.drupal.org?
I am very close to start loading content on websites, but still having a hard time understanding platforms, makefiles, and adding modules to platforms.
I am not asking questions yet, because I want to read and watch everything there is about this subject first.
I will start a different discussion for that.
Please bear with a beginner in BOA, who really needs to get this going for his livelihood.
No, that was just an example.
No, that was just an example. You could create sections of content by using taxonomy (available in Drupal core) to add categories to nodes, and show listings of each category using Views. It all depends on what exactly you want.
groups.drupal.org uses just the one subdomain, so it wouldn't use Domain Access. It uses Organic Groups to manage the groups (group membership, access control, post nodes to one or more groups, etc.).
Domain Access is for having e.g. example.com, subsite.example.com and maybe even example2.com all powered by one website (i.e., one database behind it). In Aegir you would do this by adding those other domains as domain aliases of the site via the control panel.
Note that all this is not about BOA/Aegir, it's more about using Drupal and sitebuilding in general. For general Drupal questions I'd recommend http://drupal.stackexchange.com.
Thanks a lot, ar-jan, you
Thanks a lot, ar-jan, you have been promoted to my new mentor :))
I am aware that those questions are borderline between Drupal and BOA, just wanted to know how to handle those situations in Aegir.
The discussion I will open in the next few days will hopefully be the last and it will deal exclusively with BOA: platforms, makefiles and adding modules.
If I did not understand something after testing all this, will post here.
