I did some googling and found a discussion about the pros and cons of
the /proc/mounts symlink on the LFS mailing list archives.  The
maintainer of util-linux (mount is part of util-linux) had written in
and said: "If the symlink is not necessary for the setup as used by LFS,
the instruction should be removed or be made optional."  Here's the link:

So, in the 2.0 version of the pocket linux guide the instructions will
be changed to use the old-style /etc/mtab file without a symlink.

Thanks for the tip, Daniel.

P.S. I've started a list of proposed changes for version 2.0 that is
available on the resource site at: http://my.core.com/~dhorton/linux/pocket
