Is there any way to enable this kind of switching? It sounds a bit curious. Acutally, I think this is not also I wanted.

Therefore, now I think the 'wheel' group is not the point. -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page
