>Description:
	After http://www.freebsd.org/cgi/query-pr.cgi?pr=116177,
	mdconfig returns non-zero exit status if called for non-existing
	device. This reveals a bug of src/tools/tools/nanobsd/nanobsd.sh
	sitting here from revision 1.1: inside create_i386_diskimage(),
	it does "mdconfig -d -u $MD" as last statement
	then runs the same command again as part of "trap ... EXIT" procedure
	and fails due to not masked non-zero exit status

>How-To-Repeat:
	Try to build nanobsd.

>Fix:

	Remove extra mdconfig call:
