Re: [Puppet Users] augeas and sendmail aliases

[Christopher Johnston]

I was never able to get this working properly for /etc/services, there is
support in augeas now to do the matches properly but I think the ruby
bindings are not up to date with the new changes which ended up making
puppet fail.

So it does. It works with “print”, so I thought it would work with “set” as 
well. That was my experience with `/etc/services` and `/etc/passwd`. At this 
point, I’d look at all the possible path expressions and play around a bit.

You may be stuck doing an “onlyif” after all.

You might also try the native mail alias type, as someone else suggested.

I've actually tried this in augtool and puppet and it didn't work. In 
puppet it fails silently and on first sight you would believe everything

If this works for you could you please post your version and/or other 
tricks.

If that’s the thread I’m thinking of, I was pretty heavily involved and I think 
you may have missed the point.

You want a unique path that identifies the entry you’re trying to manipulate.

  * It needs to be unique so it won’t clobber an existing entry.
  * It needs to identify the target entry so Puppet will see that it exists on 
all but the initial run.

By using 01 in the path somewhere, you’re only doing the first part, but since 
the 01 entry will never show up when Puppet looks at the file, it will assume 
it needs to add the entry (again and again). A unique path that identifies an 
entry in `/etc/aliases` would look something like this:

/files/etc/aliases/*[name = 'ftp’]

So with that, you can do things like:

set /files/etc/aliases/*[name = ‘ftp’]/name ftp

I’ve said before that Puppet encourages us to design things so they won’t hurt 
anything when run over and over, but the Augeas type seems to behave the 
opposite way by default in these “numbered item” contexts. Having said that, 
things have really improved with updates to both Augeas and Puppet and I think 
it’s an extremely valuable combo. It just takes some time to get comfortable 
with how it works.

Re: [Puppet Users] augeas and sendmail aliases

[Silviu Paragina]

I understood why that solution isn't working. Not sure if I could put 
together a similar solution.


The onlyif would probably look like
 match /files/etc/aliases/*[name='mycron' and count(value) = 2]/name 
size == 1

or
match /files/etc/aliases/*[name='mycron']/value == [list of e-mail address]

But Pienaar is right you should use the mailalias type if you can.

Is there something wrong with the puppet native type to manage this file?
