As you can see, I''ve got a very simple resource defined for testing
purposes but am seeing this error on the client. Can someone point me
in the right direction?

How to experiment with Augeas, because the docs suck (was Re: [Puppet Users] Re: augeas error)

My guess is that you are not setting a > valid structure.Yes, you have to actually set something that matches the structure of the file in question, which varies by file. Most of the lenses have shit for documentation, unfortunately, and this one is no exception. So, the easiest thing to do is to set up the file with some examples (I pulled examples from the bottom of "man 5 exports") and see what they look like: $ augtool augtool> ls /files/etc/exports/ comment[1] = /etc/exports: the access control list for filesystems which may be exported comment[2] = to NFS clients. See exports(5). comment[3] = sample /etc/exports file dir[1]/ = / dir[2]/ = /projects dir[3]/ = /usr dir[4]/ = /home/joe It took several tries to get this; it turns out the augeas lens for this file is a bit pickier than it should be: it won''t accept: /pub (ro,insecure,all_squash) Anyways, from here you can investigate the structure, like so: augtool> ls /files/etc/exports/dir[1] client[1]/ = master client[2]/ = trusty The corresponding line in the file is: / master(rw) trusty(rw,no_root_squash) Digging further: augtool> ls /files/etc/exports/dir[1]/client[1] option = rw So, if you want to add a new entry, you''d do something like this: augtool> set /files/etc/exports/dir[10000] /foo augtool> set /files/etc/exports/dir[last()]/client[1] weeble augtool> set /files/etc/exports/dir[last()]/client[1]/option[1] ro augtool> set /files/etc/exports/dir[last()]/client[1]/option[2] all_squash augtool> save Saved 1 file(s) Which creates the line: /foo weeble(ro,all_squash) Doing this in Puppet is left as an exercise for the reader. I''ll go see about getting better docs in Augeas for this thing. -Robin -- They say: "The first AIs will be built by the military as weapons."

Now that I''m more comfortable working with the schemas of each supported file, I''m seeing a potential issue when it comes to appending. Is there a way to determine the length of each object so I can avoid doing things like /files/etc/exports/dir[100] ?

Not that I''m aware of. You can use last() instead of a number (and, in fact, you have to in this case; see my long mail), but for appending the current standard is to use a very large number (like 10000). A bit weak, I know. Feel free to complain to the Augeas mailing list. -Robin On Thu, Jan 15, 2009 at 02:43:02PM -0800, windowsrefund wrote:> > Now that I''m more comfortable working with the schemas of each > supported file, I''m seeing a potential issue when it comes to > appending.
