The problem that I am running into is actually a combination of augeas 
and puppet.  The way puppet seems to work with augeas is that it runs 
the augeas commands against the existing file and creates a copy.  It 
then checks if the copy and the original are the same if they are it 
removes the copy and does nothing.  If they aren't it replaces the 
original with the copy.  In the /etc/grub.conf case this causes the 
symlink to be replaced by a regular file.  Obviously this is a problem 
because grub doesn't actually look at /etc/grub.conf.

I can work around this by telling puppet explicitly which lens to use. 
I just thought it was weird that the lens matches several files non of 
which grub actually reads directly on at least RedHat and I assume any 
other recent linux distro.
