Hello!
The ‘guix system’ command now supports two new sub-commands:
‘extension-graph’ and ‘dmd-graph’. The former produces a Dot
representation of the service extension graph, while the latter produces
a Dot representation of the graph of dmd services (part of the
documentation pasted below.)
Comments welcome!
Personally I think it’s pretty neat. :-)
Ludo’.
The ‘guix system’ command has even more to offer! The following
sub-commands allow you to visualize how your system services relate to
each other:
‘extension-graph’
Emit in Dot/Graphviz format to standard output the “service
extension graph” of the operating system defined in FILE (*note
Service Composition::, for more information on service extensions.)
The command:
$ guix system extension-graph FILE | dot -Tpdf > services.pdf
produces a PDF file showing the extension relations among services.
‘dmd-graph’
Emit in Dot/Graphviz format to standard output the “dependency
graph” of dmd services of the operating system defined in FILE.
*Note dmd Services::, for more information and for an example
graph.

That's… just insanely cool.
