Experimental Offline Installation

Currently the Agama Live ISO can only install from online repositories. For installing openSUSE Tumbleweed it is OK, but if you want to present demo at a conference then using an online repository might be a problem because of slow/not responsive internet.

For testing purposes we created a special Live DVD which installs packages from the second DVD. The recent machines usually do not include even a single DVD drive, but it should work with USB flash disks as well.

Testing

To test the offline installation follow these steps:

  1. Download the Agama installer from the systemsmanagement:Agama:Staging:DVDinstall repository
  2. Download the Tumbleweed installation DVD from the official openSUSE repository
  3. In a VM create two virtual DVD drives and attach the downloaded media to them.

Caution

The Agama ISO must be attached to the first DVD drive so the system boots from it. Otherwise it would boot the standard YaST installer from the Tumbleweed DVD.

  1. Boot the system and run the Agama installer as usually

Notes

  • The special Agama installation medium is the same as in the systemsmanagement:Agama:Staging project, the only difference is the source for the installed packages (see the details below)
  • The Tumbleweed DVD contains only a subset of packages in the online repository, the installed system might contain less packages than in online installations.
  • It works completely offline, you can install even a system without any network card!

Implementation

The trick is to change the URLs in the product definitions from https://download.opensuse.org/... to hd:/?device=/dev/disk/by-label/openSUSE-Tumbleweed-DVD-x86_64, see the details in the full diff in Git.
