Dan Nicholson adac42b6ef repo: Add add-remotes-config-dir option
This option allows a repo to explicitly opt out of adding new remotes in
a remotes configuration directory. This currently defaults to true for
system repos and false for non-system repos to maintain legacy behavior
that non-system repos don't add remotes in a configuration directory.
That would be problematic for flatpak, which specifies a remotes config
dir but adds remotes in ways that are incompatible with it.

So, what this really does is allow system repos to control whether they
want to add remotes in the config dir or not. That's important if your
flatpak repo is the system repo like at Endless.

<title>Description</title>
<para>
The <filename>config</filename> file in an OSTree
repository is a "keyfile" in the <ulink
url="http://standards.freedesktop.org/desktop-entry-spec/latest/">XDG
Desktop Entry Specification</ulink> format. It has
several global flags, as well as zero or more remote
entries which describe how to access remote
repositories.

<varlistentry>
<term><varname>fsync</varname></term>
<listitem><para>Boolean value controlling whether or not to
ensure files are on stable storage when performing operations
such as commits, pulls, and checkouts. Defaults to
<literal>true</literal>.</para>
<para>
If you disable fsync, OSTree will no longer be robust
against kernel crashes or power loss.
</para>
<para>
You might choose to disable this for local development
repositories, under the assumption they can be recreated from
source. Similarly, you could disable for a mirror where you could
re-pull.
</para>
<para>
For the system repository, you might choose to disable fsync
if you have uninterruptable power supplies and a well tested
kernel.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term><varname>min-free-space-percent</varname></term>
<listitem><para>Integer percentage value (0-99) that specifies a minimum
percentage of total space (in blocks) in the underlying filesystem to
keep free. The default value is 3.</para></listitem>
</varlistentry>
<varlistentry>
<term><varname>add-remotes-config-dir</varname></term>
<listitem>
<para>
Boolean value controlling whether new remotes will be added
in the remotes configuration directory. Defaults to
<literal>true</literal> for system ostree repositories. When
this is <literal>false</literal>, remotes will be added in
the repository's <filename>config</filename> file.
</para>
<para>
This only applies to repositories that use a remotes
configuration directory such as system ostree repositories,
which use <filename>/etc/ostree/remotes.d</filename>.
Non-system repositories do not use a remotes configuration
directory unless one is specified when the repository is
opened.

<title>/etc/ostree/remotes.d</title>
<para>
In addition to the <filename>/ostree/repo/config</filename>
file, remotes may also be specified in
<filename>/etc/ostree/remotes.d</filename>. The remote
configuration file must end in <literal>.conf</literal>; files
whose name does not end in <literal>.conf</literal> will be
ignored.
</para>
</refsect1>
<refsect1>
<title>Repository url/contenturl</title>
<para>
Originally, OSTree had just a <literal>url</literal> option
for remotes. Since then, the <literal>contenturl</literal>
option was introduced. Both of these support
<literal>file</literal>, <literal>http</literal>, and
<literal>https</literal> schemes.
</para>
<para>
Additionally, both of these can be prefixed with the string
<literal>mirrorlist=</literal>, which instructs the client
that the target url is a "mirrorlist" format, which is
a plain text file of newline-separated URLs. Earlier
URLs will be given precedence.
</para>
<para>
Note that currently, the <literal>tls-ca-path</literal> and
<literal>tls-client-cert-path</literal> options apply to every HTTP
request, even when <literal>contenturl</literal> and/or
<literal>mirrorlist</literal> are in use. This may change in the future to
only apply to metadata (i.e. <literal>url</literal>, not
<literal>contenturl</literal>) fetches.
</para>
</refsect1>
<refsect1>
<title>Per-remote GPG keyrings and verification</title>
<para>
OSTree supports a per-remote GPG keyring, as well as a
<literal>gpgkeypath</literal> option. For more information see

<title>Per-remote HTTP cookies</title>
<para>
Some content providers may want to control access to remote
repositories via HTTP cookies. The <command>ostree remote
add-cookie</command> and <command>ostree remote
delete-cookie</command> commands will update a per-remote
lookaside cookie jar, named
<filename>$remotename.cookies.txt</filename>.
