 Learned a really useful and basic basic networking command to connect to subnets beyond the subnet assigned to a given network interface.  Command is of the form:
-   # ip route add <subnet x.x.x.0>[/8|16|24] via <subnet assigned to interface> on <interface device name>
+As a regular user we must prepend `sudo` to invocations of this command, and it appears that when there's only one configured network interface that we may drop the 'on device_name' tokens at the end of the command:
 Learned as well that a user can issue a simpler command to see the local host's IP routine table:

-Specific mount invocations mentioned in chapter 6.2.  From section 6.2.2 the first <code>mount</code> invocation:
+During build of LFS system using Linux From Scratch's book 8.1, the host system was powered down and turned on again several times after completely LFS book chapter 5.  Upon each return to LFS work, Ted invokes six `sudo mount` commands to set up both real and virtual Linux file systems.  These mounts are in effect on the host computer, and they're also visible within the $LFS environment.  The first mount puts the root file system '/' of the LFS instance at the host's mount point /mnt/lfs:
-    mount -v --bind /dev $LFS/dev

Ted noting the backslashes for line continuation don't work, and thinking on this syntax it makes sense that we need separate each mount invocation, as these are complete commands.  Otherwise the second `mount` is parsed by the shell as an rgument to the first appearance of `mount` . . .
