Was the Minimal Install customization feature was released for cubic?

Eugene,

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

----------------------------------
Summary
----------------------------------
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.

Got it, thank you :)
