what I had hoped to get out of disko was mostly declaratively defined zfs datasets, that I can just create by adding them to my config, but it seems I was wrong and that isn't a thing.

Yes, it's just for initial setup by default.

If you feel adventurous and have a tested backup of your data you can try rerunning the system.build.formatScript which should be idempotent but please review the script and don't blame us if it eats your data 😇

If you want to start out with your own module and just need a solution specifically to add zfs datasets, it might be helpful to know about

nixosConfigurations.$hostname.config.disko.devices.zpool.$poolname.datasets."$dataset"._create which gives you the command diskos formatScript would use to create the dataset. That's already idempotent. Sylvie (she/it) 🏳️‍⚧️

I've removed "latest" from the url but the installer (and terminal) crashes when using Disko install
EDIT: it runs out of Memory
Using a pendrive and 16gb of RAM

Try again with the -j 1 flag.

Try again with the -j 1 flag.

Actually since this is -install the flag is probably --option max-jobs 1

added after 10pm--`
