guarantee that the store items it provides will indeed remain available
for as long as @var{ttl}.
@item --nar-path=@var{path}
Use @var{path} as the prefix for the URLs of ``nar'' files
(@pxref{Invoking guix archive, normalized archives}).
By default, nars are served at a URL such as
@code{/nar/gzip/@dots{}-coreutils-8.25}. This option allows you to
change the @code{/nar} part to @var{path}.
@item --public-key=@var{file}
@itemx --private-key=@var{file}
Use the specific @var{file}s as the public/private key pair used to sign
the store items being published.
The files must correspond to the same key pair (the private key is used
for signing and the public key is merely advertised in the signature
metadata). They must contain keys in the canonical s-expression format
as produced by @command{guix archive --generate-key} (@pxref{Invoking
guix archive}). By default, @file{/etc/guix/signing-key.pub} and
@file{/etc/guix/signing-key.sec} are used.

From: LemonBoy <thatlemon@gmail.com>
Date: Fri, 10 Mar 2017 16:29:47 +0100
Subject: [PATCH] Add bound checking to all srfi-4 vector allocations.
Do what C_allocate_vector already does and prevent the creation of a
vector that's too big or too small.
We should be very careful to avoid the latter case because the
allocation size is directly fed into `malloc' as 'x + sizeof(C_header)'
thus making possible to successfully allocate a vector smaller than the
C_header structure and get C_block_header_init to write over
uninitialized memory.
To reduce code duplication, type checking is moved from each of the
make-*vector procedures to the common "alloc" helper procedure.
