+Often, it is desired to run F<novaboot> on the server to boot the
+default configuration. To make this easier to configure, the
+C<default_cmd> can be set to:
+
+ run_novaboot <nbscript> [<extra args>...]
+
+This command will execute C<novaboot> with the F<\<nbscript>> script
+as an argument and passes it a few switches with values from the
+F<$HOME/.novaboot-shell> configuration file. Specifically, it will
+pass all switches from the C<target_config> variable, C<--reset-cmd>
+and C<--remote-cmd> switches with the values of C<reset_cmd> and
+C<console_cmd> variables respectively (see above) and C<--server>
+switch.
+
+Therefore, to boot the default configuration as specified in the
+F<default_boot> script, it is sufficient to set C<default_cmd> to:
+
+ run_novaboot ./default_boot --interactive
+
+To have different default configuration for different users, one can
+use the C<$NB_USER> variable as outlined above. The simplest example
+is perhaps this command:
+
+ run_novaboot ./default_boot-"$NB_USER" --interactive
+
