Return true if CHANNEL is the 'guix' channel.

Return a new channel introduction: COMMIT is the introductory where authentication starts, and SIGNER is the OpenPGP fingerprint (a bytevector) of the signer of that commit.

Return the derivation of the profile containing INSTANCES, a list of channel instances. If BUILT-IN-BUILDERS is provided, it should be a list of strings and this will be used instead of the builtin builders provided by the build daemon for store connections used during this process.

Convert STR, an OpenPGP fingerprint (hexadecimal string with whitespace), to the corresponding bytevector.

Authenticate the given COMMIT of CHANNEL, available at CHECKOUT, a directory containing a CHANNEL checkout. Raise an error if authentication fails.

Return the list of channels corresponding to entries in PROFILE. If PROFILE is not a profile created by 'guix pull', return the empty list.

Return a list of <channel-news-entry> for CHANNEL between commits OLD and NEW. When OLD is omitted or is #f, return all the news entries of CHANNEL.

Return a profile manifest with entries for all of INSTANCES, a list of channel instances. By default, build for the current system, or SYSTEM if specified. If BUILT-IN-BUILDERS is provided, it should be a list of strings and this will be used instead of the builtin builders provided by the build daemon for store connections used during this process.

Return the channel ENTRY corresponds to, or #f if that information is missing or unreadable. ENTRY must be an entry created by 'channel-instances->manifest', with the 'source' property.

Return code (an sexp) to build CHANNEL. When INCLUDE-INTRODUCTION? is true, include its introduction, if any.
