list-runtime-roots: Canonicalize store items.
Looking at 'addAdditionalRoots' in libstore/gc.cc, it looks like it

Jan Nieuwenhuizen 2e009ae7cd
daemon: Flush the sink upon 'exportPath' errors.
Prior to this change, errors such as wrong permissions on
/etc/guix/signing-key.sec would give:

  guix-daemon: nix/libutil/serialise.cc:15: virtual nix::BufferedSink::~BufferedSink(): Assertion `!bufPos' failed.

This patch correctly propagates the error to the client and thus changes
that to:

  error: build failed: file `/etc/guix/signing-key.sec' should be secret (inaccessible to everybody else)!

* nix/nix-daemon/nix-daemon.cc (performOp): Wrap 'exportPath' call in
'try' block.

daemon: Define 'NIX_STORE' before invoking 'guix perform-download'.
Reported by rohit yadav <rohityadav@utexas.edu>
at <https://lists.gnu.org/archive/html/guix-devel/2017-02/msg00191.html>.

This fixes a regression whereby 'guix perform-download' would always see
NIX_STORE as unset and thus use "/gnu/store", leading it to miscompute
the hydra.gnu.org content-addressed URLs when the store file name is not
"/gnu/store".

* nix/libstore/builtins.cc (builtinDownload): Add 'setenv' call for
'NIX_STORE'.

Ludovic Courtès 9a8f9f84cc
daemon: Buffer data sent to clients by the 'export-path' RPC.
Before that we'd have STDERR_WRITE round trips for very small amounts of
data, ranging from a few bytes for the metadata of nars to the size of
one file being exported.

With this change, something like:

  guix archive --export /gnu/store/5rrsbaghh5ix1vjcicsl60gsxilhjnf2-coreutils-8.25 | dd of=/dev/null

reports a throughput of 35 MB/s instead of 25 MB/s before.

Previously files in the Nix store were owned by root or by nixbld,
