It is sometimes desirable to update the guix
package itself (the
package defined in (gnu packages package-management)
), for
example to make new daemon features available for use by the
guix-service-type
service type. In order to simplify this task,
the following command can be used:
make update-guix-package
The update-guix-package
make target will use the last known
commit corresponding to HEAD
in your Guix checkout,
compute the hash of the Guix sources corresponding to that commit and
update the commit
, revision
and hash of the guix
package definition.
To validate that the updated guix
package hashes are correct and
that it can be built successfully, the following command can be run from
the directory of your Guix checkout:
./pre-inst-env guix build guix
To guard against accidentally updating the guix
package to a
commit that others can’t refer to, a check is made that the commit used
has already been pushed to the Savannah-hosted Guix git repository.
This check can be disabled, at your own peril, by setting the
GUIX_ALLOW_ME_TO_USE_PRIVATE_COMMIT
environment variable. When
this variable is set, the updated package source is also added to the
store. This is used as part of the release process of Guix.
