taken care of authorizations.

@node Primary URL
@section Primary URL
Channel authors can indicate the primary URL of their channel's Git
repository in the @file{.guix-channel} file, like so:
@lisp
(channel
(version 0)
(url "https://example.org/guix.git"))
@end lisp
This allows @command{guix pull} to determine whether it is pulling code
from a mirror of the channel; when that is the case, it warns the user
that the mirror might be stale and displays the primary URL. That way,
users cannot be tricked into fetching code from a stale mirror that does
not receive security updates.
This feature only makes sense for authenticated repositories, such as
the official @code{guix} channel, for which @command{guix pull} ensures
the code it fetches is authentic.
