Fixes <http://bugs.gnu.org/18534>.
* guix/scripts/pull.scm (with-environment-variable, with-PATH): New
macros.
(temporary-directory, first-directory, interned-then-deleted): New
procedures.
(unpack): Rewrite to do the unpacking in the current process rather
than as a separate derivation.
(%self-build-file): New variable.
(build-from-source): New procedure.
(build-and-install): Use it.
* guix/build/pull.scm (build-guix): Rename 'tarball' argument to
'source'. Remove #:tar and #:gzip parameters, as well as 'tar'
invocation. Remove 'scandir' invocation. Wrap body in
'with-directory-excursion'.
* build-aux/build-self.scm: New file.
* Makefile.am (EXTRA_DIST): Add it.
* gnu/system/vm.scm (system-qemu-image/shared-store): Add
#:disk-image-size and #:full-boot? parameters and honor them. Pass
'#:copy-inputs? full-boot?', and change #:inputs argument.
* guix/scripts/system.scm (system-derivation-for-action): Pass
#:disk-image-size to 'system-qemu-image/shared-store'.
* doc/guix.texi (Invoking guix system): Mention use of '--image-size' in
conjunction with '--full-boot'.

and suggestions.

(patch-and-repack): Invoke 'package-derivation' with #:graft? #f.
(package-source-derivation): Likewise. Do not use (%guile-for-build)
in call to 'patch-and-repack', and we could end up using a grafted
Guile.

instead of 'package-full-name'.

'parameterize'.
* doc/guix.texi (Security Updates): New node.
(Invoking guix build): Document --no-graft.
* guix/scripts/environment.scm (show-help): Align --pure and

'GUIX_BINARY_SUBSTITUTE_URL' environment variable.
* test-env.in: Invoke 'guix-daemon' with '--substitute-urls'.
* tests/substitute-binary.scm: Set '%cache-url' to the value of
'GUIX_BINARY_SUBSTITUTE_URL'.
* guix/scripts/lint.scm (check-start-article): use "string-ci=?" instead of
"string=?".

Handle the case where 'find-best-packages-by-name' returns '().
