[bug#28377] [PATCH 00/10] Allow users to specify the UUID of disk images

From: Ludovic Courtès
Subject: [bug#28377] [PATCH 00/10] Allow users to specify the UUID of disk images
Date: Wed, 6 Sep 2017 23:51:30 +0200


This is a followup to
<>: it’s about
making it possible to specify the UUID of the root partition of the disk

To get there, this patch series does a few things:

  1. Give a 2nd argument to ‘uuid->string’ et al., which is the name of
     the UUID format.

  2. Move UUID-related code to (gnu system uuid).

  3. Introduce a <uuid> record type that ties together a bytevector and
     a symbol specifying the UUID type (DCE, ISO9660, etc.).  This
     allows ‘uuid->string’ to generate a string in the “right” format as
     expected by tools such as GRUB.

  4. Finally, generate a UUID for generated images.

Tested with both an ISO and an ext4/qcow2 image.

Feedback welcome!


Ludovic Courtès (10):
  vm: Allow partitions to be initialized with a given UUID.
  file-systems: Add UUID type dictionaries.
  services: base: Import the closure of (gnu build file-systems).
  file-systems: Introduce (gnu system uuid).
  services: file-system: Use 'file-system->spec'.
  system: Introduce a disjoint UUID type.
  system: Serialize the UUID type in the "parameters" file.
  uuid: 'uuid' macro supports more UUID types.
  vm: Allow users to specify a UUID for the root partition.
  vm: Generate a UUID to identify the root file system.
