I see them. The error messages are a bit obscure and the lens seemed to 
be working. Is there a FAQ on reading the error messages?

if you put the settings file from [1], or if you have cobbler 
installed.. there is nothing special about this file, you can do the 
folloing from augtool:

augtool> set /files/etc/cobbler/settings/allow_duplicate_hostnames 1
augtool> save
Saving failed
augtool> get /augeas/files/etc/cobbler/settings/
error/  lens    path
augtool> get /augeas/files/etc/cobbler/settings/error/message
/augeas/files/etc/cobbler/settings/error/message = Failed to match
     { /value/ = /[^\001-\004\t\n 
#:@]+|\"[^\001-\004\n\"]*\"|'[^\001-\004\n']*'/ }({ /value/ = 
/[^\001-\004\t\n #:@]+|\"[^\001-\004\n\"]*\"|'[^\001-\004\n']*'/ })*
   with tree
     { "ksdevice" = "bootif" } { "lang" = "' '" } { "text" = "~" }
augtool>
