This prevents conflicting variants of python-prompt-toolkit from being
installed, which prevented jupyter from being installed.
* gnu/packages/python-xyz.scm (python-ipython)[propagated-inputs]: Replace
python-prompt-toolkit with python-prompt-toolkit-2.
(python-widgetsnbextension)[propagated-inputs]: Do not use
prompt-toolkit-2-instead-of-prompt-toolkit on python-ipykernel.
(python-ipywidgets)[propagated-inputs]: Do not use
prompt-toolkit-2-instead-of-prompt-toolkit on python-ipython.
(python-jupyter-console)[propagated-inputs]: Do not use
prompt-toolkit-2-instead-of-prompt-toolkit on python-ipykernel.
(prompt-toolkit-2-instead-of-prompt-toolkit): Remove variable.
* gnu/packages/machine-learning.scm (python-iml)[propagated-inputs]: Do not
use prompt-toolkit-2-instead-of-prompt-toolkit on python-ipython.
Apply the following upstream fix:
ea13e06563.
* gnu/packages/mate.scm (libmateweather)[source]: Fix tests by renaming
America/Godthab timezone to America/Nuuk.
* build-aux/git-authenticate.scm (%use-historical-authorizations?)
(%introductory-commit): New variables.
* build-aux/git-authenticate.scm (git-authenticate): Use pass the empty
list as #:default-authorizations when %USE-HISTORICAL-AUTHORIZATIONS? is
false.
This is useful when people run "guix time-machine -C channels.scm",
where 'channels.scm' misses channel introductions.
* guix/channels.scm (%default-channel-url): New variable.
(%default-channels): Use it.
(ensure-default-introduction): New procedure.
(latest-channel-instance): Call it.
This should come before patching, authentication, etc.
* guix/channels.scm (latest-channel-instance): Add #:validate-pull
parameter and honor it. Return a single value: the instance.
(ensure-forward-channel-update): Change 'instance' parameter to 'commit'
and adjust accordingly.
(latest-channel-instances): Adjust to 'latest-channel-instance' changes.
* guix/scripts/pull.scm (warn-about-backward-updates): Change 'instance'
parameter to 'commit' and adjust accordingly.
* tests/channels.scm ("latest-channel-instances #:validate-pull"):
Likewise.
Fixes <https://bugs.gnu.org/22883>.
* guix/channels.scm (<channel>)[introduction]: New field.
(<channel-introduction>): New record type.
(%guix-channel-introduction): New variable.
(%default-channels): Use it.
(<channel-metadata>)[keyring-reference]: New field.
(%default-keyring-reference): New variable.
(read-channel-metadata, read-channel-metadata-from-source): Initialize
the 'keyring-reference' field.
(commit-short-id, verify-introductory-commit)
(authenticate-channel): New procedures.
(latest-channel-instance): Call 'authenticate-channel' when CHANNEL has
an introduction.
* tests/channels.scm (gpg+git-available?, commit-id-string): New
procedures.
("authenticate-channel, wrong first commit signer"):
("authenticate-channel, .guix-authorizations"): New tests.
* doc/guix.texi (Invoking guix pull): Mention authentication.
* guix/git-authenticate.scm (authenticated-commit-cache-file)
(cache-authenticated-commit, previously-authenticated-commits): Add
'key' parameter and honor it.
* build-aux/git-authenticate.scm (git-authenticate): Pass
"channels/guix" as the key.
Fixes <http://issues.guix.gnu.org/41704>.
* gnu/packages/package-management.scm (nix)[arguments]: Add
‘--sysconfdir=/etc’ configure flag and override it during installation.

An old snippet was causing the build to fail when using Emacs 27.
* gnu/packages/emacs-xyz.scm (emacs-yasnippet)[source]: Use git-file-name, and
remove obsolete snippet.
[phases]{home}: New phase. This allows the rebindings test to pass.
{make-tests-writable, delete-rebinding-test}: Remove phases.
[description]: Re-indent.
Suggested by Maxim Cournoyer via IRC.
* doc/guix.texi (The Hurd in a Virtual Machine): Explicitly mention that
hurd-vm and childhurd are two names for this service.
