`disko` is always formatting about disko HOT 6 CLOSED

Partial application of disko config is on the agenda. As is an idempodent variant of the createScript. Will try to tackle this after my current pr is reviewed and merged

from disko.

if you use diskoScript it will format all the drives, since today (#568) this shouldn't happen anymore if you just use the formatScript with --mode format or --mode create. but since this was merged today it's still not fully tested :)

Yes, that's expected behavior. Might be a good idea to mention that more explicitly in the README.

For the data disk I am not able to find an option in disko that allows to not format a partition if the condition are already met, for example the table is already gpt, the size is correct, the filesystem is correct, ...

It's always a balance between features and the complexity of the implementation. PRs would be welcome, but what's your use case here? You should be good to re-install by just omitting your data disk from the config here.

Currently:

1. I have to connect my small server to a monitor, keyboard, mouse, insert the usb pen
2. Boot
3. Install Fedora Server
4. Run my ansible playbook from my laptop
5. Wait for Argo CD to finish its magic
6. Shutdown
7. Disconnect monitor, keyboard, mouse and usb pen
8. Start

The fact that using nixos-anywhere would allow me to reinstall everything via ssh in a declarative way it is of great interest.

Currently the ansible playbook does everything even formatting/mounting (if necessary), and it works in a real declarative way so if the partition size/format is the same no changes are applied.

I was a bit sceptical at the beginning but never lost data in 8 months.

My use case can be resumed in the nix script from my first post, just 2 disks: one for the OS the other for the data, no changes to the playbook no changes applied.

You are right you could simply comment the data disk section after the first setup and manually run the fdisk/mkfs/... commands but they break a bit the declarative spirit.

For now the setup is very simple just 1 disk, 1 partition. If in the future the number of disks increases and/or the filesystems setups increase in complexity, a real "declarative" disko would be very welcome.

Anyway thanks for you effort.

Super I will keep an eye on the project.
Thanks

Is this still expected? I just nuked my installation (luckily without any data, as it was new) after changing my ZFS dataset on a secondary drive. I assumed at most it would format the secondary drive, but apparently it nuked every drive included in my disko configuration.

What would be the right procedure for updating my ZFS dataset without formatting the drives?
Thanks
