=head1 SYNOPSIS

B<mknb> I<arch>


=head1 DESCRIPTION

The B<mknb> command is run by xCAT automatically, when xCAT is installed on the management node.
It creates a network boot root image (used for node discovery, BMC programming, and flashing)
for the same architecture that the management node is.  So you normally do not need to run the B<mknb>
command yourself. Presently, only the arch x86_64 is supported.
