<title>Description</title>
<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>.
