+Subject: [PATCH] lxc-busybox: make some OpenSSH tools optional
+
+Currently, when installing OpenSSH in a Busybox container, the template searches
+for all the OpenSSH client binaries available in the Debian distro package. The
+included tools might differ from distro to distro, so make part of the tools
+optional. The mandatory tools, without which installing OpenSSH fails, are
+"sshd" for the server and "ssh" and "scp" for the client.
