Today I was trying to write a script for partitioning disks using fdisk (since that seemed like the simplest option).

When going through fdisk the first time and pressing n for new partition, the first prompt asked if I wanted to make a primary or extended partition. I q quit. On going back through the same procedure, the first prompt was for what sector I wanted to be first. Since I did not w write any changes, nothing should have changed, right?

If I can't predict when fdisk will give me what prompts, then I can't reliably script it. Most stuff I read recommended sfdisk for scripting, but noted that SUN disk labels are not supported. Since I want to install ZFS on root, my understanding that won't work.

So how do I predict the prompts from fdisk, or what is an alternative for scripted partitioning that supports both UEFI and ZFS?

Note: I am comfortable scripting this because I have the /dev/disk/by-id/ of each device, so as not to be confounded by changing disk labels or UUIDs.

    IIRC parted supports UEFI, but dunno about ZFS. In any case, wouldn't it be better to use ZFS tools directly once you have created the partition? IMHO parted also makes for better scripting. – muru Jun 27 '19 at 17:53
  • Well, I'm making a mix of ZFS and other types of disk but that is a good point. I can just do the regular stuff with parted and use ZFS for the ZFS stuff. – Stonecraft Jun 27 '19 at 18:06

    Somehow I was under the impression that parted wasn't scripting friendly, but after you reminded me about parted I found this: https://unix.stackexchange.com/questions/200582/scripteable-gpt-partitions-using-parted – Stonecraft Jun 27 '19 at 18:10
