1707	been updated to include a symlink to the on-disc version of
1708	&man.pkg.8; in the <filename
1709	  class="directory">packages/</filename> structure on the
1710	DVD installer.  This allows the &man.pkg.7; bootstrap utility
1711	to properly locate the <filename>Latest/pkg.txz</filename>
1712	package on the DVD when <literal>REPOS_DIR</literal> is set to
1713	<filename class="directory">/dist/packages/repos</filename>,
1714	eliminating the need for a network connection or explicitly
1715	providing the path to the version included on the DVD
1716	installation medium.</para>

1720	provide support for building virtual machine disk images as
1721	part of the release build process using &man.mkimg.1;.  The
1722	disk image formats currently supported include QCOW2, VHD,
1723	VMDK, and raw formats.  See &man.release.7; for additional

1727	&os;&nbsp;Release Engineering build tools have been updated to
1728	provide support for building &os; virtual machine disk images
1729	for the &microsoft;&nbsp;Azure cloud hosting platform.  This
1730	functionality is not connected directly to the default
1731	<literal>release</literal> &man.make.1; target, however can be
1732	invoked by specifying the <literal>vm-azure</literal> target
1733	directly.</para>
