I don't see why there is any confusion here. Before you mount to a directory, the mount point is...just a directory. I don't understand the question about directory inodes with mounting - a created directory does of course take up some space on the disk, same as any other file. I think you are just seeing additional complications where there is none. -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page
