How do I use a kickstart script from RedHat in Ubuntu without altering the ISO

I'm trying to automate the Ubuntu installation process as part of a migration from RedHat, and I have a working kickstart script that I would like to modify for Ubuntu.

I have read several answers here and official Ubuntu tutorials, so I did manage to use the graphical tool to generate the KS script. However, I don't want to alter the ISO image at this point; instead I want to load the KS script from the installation menu. In RedHat you need only press e and then indicate the path to the script (currently hosted in an HTTP server).

Is there a way to do this in Ubuntu? My plan is to test the script in Virtualbox until I get the desired result, and alter the ISO only then.

Upon booting to the ISO it will give you Try.... Try...Without Installing, etc. Arrow to the one you want then press F6 then press ESC it gives you the boot line right there in edit mode ready to go. When done with your modifications you just press Enter.

In ubuntu, it is called a preseed file.

There are several ways to tell the installer to use a preseed file:

  • place it in the boot image as preeseed.cfg (which you don't want to do) or reference it on the kernel command line as preseed/file=/cdrom/preseed2.cfg
  • add the preseed to the installer's initrd (probably not what you want)
  • reference it in the kernel command line as preseed/url=http://host/path/to/preseed.cfg (This could be hand edited after booting the installer image to the menu.)
  • supply the path to the preseed file in dhcp using option vendor-class-identifier="d-i" and filename="url" (Note: it may be a good idea to scope this carefully.)
  • If you were network booting rather than booting an ISO image, you could also supply the preseed path in the kernel command line in the pxe boot config file

The preseed file is Ubuntu-specific, I'd have to review the documentation and learn how to use that one. What I'm looking for at the moment is a means to run the adapted kicstart file from RedHat.

Kickstart is specific to RedHat, but this looks promising: https://help.ubuntu.com/community/KickstartCompatibility

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
