How to change the default partitioning scheme during install (partman config)?

  • 772

Last time I was installing Ubuntu, I ran it live from usb and changed the partman's config for the default partitioning scheme.

That was the easiest way to get full disk encryption, yet have the custom partition sizes (larger boot, no swap). The alternative would be using gparted and manually configuring LUKS, a far cry from simply ticking "encrypt" setting at the install (see https://askubuntu.com/a/918030/47073 for the stupid amount of steps required).

Unfortunately I forgot where the partman's config is with the default partitioning scheme.

system-installation encryption partitioning

  1. Have figured this out while installing.

    The configurations are in /lib/partman/recipes*, e.g. /lib/partman/recipes-amd64-efi/. For me, editing the 30atomic file did the trick.

    See https://askubuntu.com/a/678074/47073 for the details of editing.
