I have looked at similar questions such as this and this, but the answers seem to focus on how to set up virtual hosting. I'm not an expert on it, but I'm more worried about what to do after I have that working. Here's my example:

Let's say I'm a SaaS provider of a service foo. I host at fooservice.com. For each user, they get their own subdomain bob.fooservice.com. I'm pretty sure I can get that part covered. There is lots of documentation on it. Let's also assume that Bob wants the service to appear as a subdomain of his site awesomebob.com. He wants it to be foo.awesomebob.com. I know that what Bob has to do is add a CNAME record from foo.awesomebob.com -> bob.fooservice.com. My question is what do I have to do to make sure that all works on my fooservice server.

  1. Do I have to do anything special to make sure that the address bar stays foo.awesomebob.com?
  2. How can I make sure that only the CNAME foo.awesomebob.com is able to do the domain mapping? On sites like shopify and wordpress, they make you input the domain that is being used for the mapping through an admin panel. What is going on behind the scenes here?
  3. From what I've researched, this would be impossible to do with a single IP address and still have SSL support. Is that correct?

I was given an old server from work that I wanted to convert to a home file server. So I wanted to just do a clean install of Ubuntu server. Problem is, when I get to the partition screen I don't get the normal options. Instead of getting the normal options, its skips straight to the confirmation screen and I have 3 options:

  1. Help on partitioning
  2. Undo changes to partitions
  3. Finish partitioning and write changes to disk.

1 is obviously not helpful here, 2 just gives me a blank screen, and 3 tells me that "No root file system is defined." If I were to make a guess I would say that the hard drive is most likely encrypting and perhaps that is causing the problem?

I have no interest in the data that's already there. I just want a fresh install. I can probably get the root password to the machine if I have to. Any ideas?
