Was the Minimal Install customization feature was released for cubic?

Asked by Eugene Shulga

As mentioned in this thread:

...the possibility to customize Ubuntu "Minimal Install" was in development, wasn't it released yet?

I just tried Cubic 2021.01.42 with Ubuntu Focal mini.iso, and still getting an error.

No. Cubic will never be able to support this...

Customizing a Live ISO is different than using mini.iso.

"The minimal iso image will download packages from online archives at installation time instead of providing them on the install media itself." (https://help.ubuntu.com/community/Installation/MinimalCD)

The differences are:

The Live ISO
- Contains all the packages you need to install your system.
- Doesn't let you chose which packages are installed during installation (because you've already set these up in the Linux file system before creating the ISO).

The mini.iso
- Has *no* packages on it
- Lets you chose which packages you want to install during installation time
- Downloads those packages and installs them to your computer

The Live ISO and the mini.iso are like apples and oranges. The concepts are different and they do completely different things.

Essentially, there is *no* Linux file system on a mini.iso for you to customize, so there's nothing for Cubic to do with a mini.iso.

(Technically, the mini.iso has a Linux kernel that *bootstraps* the ISO, but that is not what gets installed to your system).

You may be already aware:

1. The mini.iso is used when...

- You don't have enough space on your install media.
- The mini.iso is ***NOT*** a minimal install of Ubuntu
- For example, suppose your PC only boots to CD.
    The maximum size of data on a CD is 700 GB.
    But you want to install Ubuntu 20.04.
    The "ubuntu-20.04-desktop-amd64.iso" file is 2.7 GB, and it will not fit onto your CD.
    In that case you would burn a mini.iso to the CD.
    Once the mini.iso boots up, it will establish a network connection and download the rest of the files needed for installation.

2. Cubic is used when...

- You want a ***MINIMAL*** (customized) installation of Ubuntu
- ~OR~, you want a ~FULL~ (customized) installation of Ubuntu
- You would like to install this customized OS to multiple systems
- You would like a customized recovery ISO so you can reinstall your system with your customization
- For a for a minimal install, select the packages you do NOT want on Cubic's packages page (the *.iso file size stays the same).
- Alternatively, remove packages/software you do not want on Cubic's Terminal page. This will result in a smaller *.iso file.
