Looks like a typo in the code: bundle agent edit_sshd { files: "$(configfiles.files[sshdconfig])" instead of bundle agent edit_sshd { files: "$(configfiles.files[sshd])"

Code on page 59

The code as is printed on page 59 does not work. The code from the git repository is different in the classes: line and it does work on Linux only, still fails to do anything on NetBSD. Please update the code in the book, ebook, thanks.

The code on page 59 does work on Linux. FYI unfortunately it fails to do anything on NetBSD. : [/home//cfe_code] # uname -a NetBSD 6.1.4_PATCH NetBSD 6.1.4_PATCH (MYKERNEL) #1: Mon May 5 00:13:57 NZST 2014 root@server:/usr/obj/sys/arch/i386/compile/MYKERNEL i386 : [cfe_code] # cf-agent -KIf ./p59.cf : [cfe_code] # I plan to test it later on AIX, HPUX and Solaris.

Note from the Author or Editor:
Hi, thank you for your submission. Unfortunately I cannot make sure the examples work in every possible platform. I will add a note about this in the next edition - all the examples are tested under Linux (and some of them on OS X). That being said, the example you mention should be fairly platform-independent, since it doesn't use any system-specific features. I will look into it.

"Both include the same basic technology and" Might be worth rephrasing this sentence, and replace the "basic technology" with something better, like proven or robust or trusted technology.
