[PATCH 00/10] Allow users to specify the UUID of disk images |
|
Date: |
Wed, 6 Sep 2017 23:51:30 +0200 |
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!

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.

Yes. In Scheme only #f is false; any other value is true.
I’ve replaced “is the UUID…” by “specifies the UUID…”, which is
hopefully clearer.
I’ve now pushed the whole series. Thanks for reviewing!
