This will be useful in the unit test added by the next commit. It just passes OSTREE_REPO_PULL_FLAGS_MIRROR to the call to ostree_repo_pull_from_remotes_async().

|
|
<para>
|
|
OSTree has the ability do pulls not just from configured remote
|
|
servers but also from peer computers on the LAN and from mounted
|
|
filesystems such as USB drives. This functionality requires the use
|
|
of collection IDs and GPG verification.
|
|
</para>
|
|
<para>
|
|
The <command>find-remotes</command> command searches for remotes
|
|
which claim to provide one or more of the given COLLECTION-ID REF
|
|
pairs and prints information about them, with remotes sorted by
|
|
latency (Mounts > LAN > Internet). By default, OSTree searches for
|
|
remotes in configuration files, on mounted filesystems (in a
|
|
well-known location), and on the LAN using Avahi. Searching for LAN
|
|
remotes requires OSTree to have been compiled with Avahi support,
|
|
and it requires an Avahi daemon to be running. You can override the
|
|
default set of finders (sources for remotes) using the
|
|
<option>--finders</option> option documented below.
|
|
</para>
|
|
<para>
|
|
The <command>create-usb</command> command is the recommended way to
|
|
put refs on a USB such that <command>find-remotes</command> will
|
|
discover them. See
|
|
<citerefentry><refentrytitle>ostree-create-usb</refentrytitle><manvolnum>1</manvolnum></citerefentry>.
