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

[Ludovic Courtès]

Hello!

This is a followup to
<https://debbugs.gnu.org/cgi/bugreport.cgi?bug=27735#31>: it’s about
making it possible to specify the UUID of the root partition of the disk
image.

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!

Ludo’.
