After so many years of installing a new Leap release using the Upgrade Option at boot time or preserving previous disk partitions and LVM configuration with the Install option, I can not believe that Leap 16.0 will not allow me to install the OS without destroying current partitions and volume groups. Agama will not allow me to do what I want when overwritying existing partitions and lvs. The only way I was able to do that is having a previous Leap release and install the upgrade to 16.0 script. But, what happens if I have another Linux flavor installed?. The expert partitioning tool should be recovered from trash on OS Leap 16.0.
Without knowing your exact requirements, Agama is capable of preserving existing storage partitions and LVM configurations rather than destroying them automatically. Users often miss the advanced storage options and workflows in Agama.
Did you consult the Agama storage configuration guide?
The Expert Partitioning feature in the Agama installer does exist.
But it is so poor and confusing that it easily beats even the Expert Partitioning feature in the Fedora installer.
Agama version used to Leap 16.0 have that limitations; I.e. Agama 21 can use your LVM without problem:
Maybe. I don’t try the Fedora installer. But you can do a lot of things and a lot of others are in twmhe way.
Well, Agama 21 is good enough but the version used for Leap 16.0 had a quite basic user interface (being nice…) and unfortunately an Agama 21 devel version for Leap 16 which should appear here is still missing.
We should have better luck with Leap 16.1 (still alpha though).
Isn’t there a fresh install iso?
Official Agama Live ISO
Agama is a multi-product installer. It means that you can install different distributions using a single medium. In close collaboration with the openSUSE project, the current image allows installing openSUSE Tumbleweed, openSUSE Leap 16.0 , openSUSE Micro OS and openSUSE Slowroll (experimental).
What you linked installs Tumbleweed, Slowroll and Micro-OS, not Leap.
The Leap 16.1 installer is “fresh” but 16.1 is still in alpha test, not for normal users yet.
As detailed above, there is a repo for a “fresh” Agama for Leap 16.0 but it is still empty at the time of writing this.
