This is only a guess, but is Augeas doing a STRING comparison of the values
instead of a NUMERICAL one?
String-wise, "7000" < "80" but numerically it's the other way around.
Can you try setting the current value to '1' and see if Augeas wants to change
it to 784009728. If it does, then that's the issue.
As to WHY it would be doing a string-wise comparison, I don't know. It could
be down to the version of Augeas or the Puppet agent. Try upgrading to the
latest and test it again...

Subject: [Puppet Users] Augeas question a<b
Hi,
I'm having some 'strange' issues with augeas and an onlyif statement
This is my code
augeas { "classx_sysctl_shmmax":
incl => '/etc/sysctl.conf',
lens => 'Sysctl.lns',
changes => "set kernel.shmmax ${sysctl_kernel_shmmax}",
onlyif => "get kernel.shmmax < ${sysctl_kernel_shmmax}",
}
I only want to change the kernel.shmmax in /etc/sysctl.conf when the
value is greater than what is currently configured.
For example
kernel.shmmax defauls to 784009728 and I changed it manually to
784009729 (so +1)
=> When puppet runs, nothing needs to be done (as expected)
kernel.shmmax defaults to 784009728 and I changed it manually to
784009727 (so -1)
When puppet runs, it wants to change the value (as expected)
-kernel.shmmax = 784009727
+kernel.shmmax = 784009728
notice: /Stage[main]/Classx/Augeas[classx_sysctl_shmmax]/returns:
current_value need_to_run, should be 0 (noop)
So for now, everything looks fine, however ...
If I change the value to something really small, like from 784009728
to 84009728 (removed the first digit), pupppet does not want to change
it anymore.
What I can see is that puppet/augeas only evaluates values correctly
as long as the number of digits stays the same, so
100 is less than 101
101 is greater than 100
but 99 is greater than 100 ?!? :-(
Anyone an idea how I can configure augeas to do this correctly ??
Regards,
Rene
