These are related things, but somewhat separate. This change should make it

This allows easily processing an individual job by id. This may be useful to
use manually, but also when processing jobs in parallel, as forking doesn't

And use it for the hosting the inferiors, rather than computing the guix
package at runtime. This simplifies the behaviour when the Guix Data Service
is deployed as a Guix package.
This runs Sqitch on startup, which should make managing the database easier,
as you just have to restart the service with this option, and the database
should be updated if necessary.
This is a service designed to provide information about Guix. At the
moment, this initial prototype gathers up information about packages,
the associated metadata and derivations.
The initial primary use case is to compare two different revisions of
Guix, detecting which packages are new, no longer present, updated or
otherwise different.
It's based on the Mumi project.
