then I suggest just enforcing coding standards at your organization to
avoid using "." as "and"...a simple shell script with grep could find
these cases and (for example) prevent code from being checked into your
version control system.

We use rPath for this: http://www.rpath.com
As with Satellite, not free. But an exceptionally powerful tool that
lets you build and manage an entire set of appliances (OS + application)
and supports nifty things like rollback, migration, and development staging.

This sounds like a bug...shouldn't the syntax parser prevent you from
setting the value larger than an unsigned int? An arbitrary "9"
or whatever isn't very useful.

Well since cfengine edits the file in memory and then does a comparison
to the on-disk version before making commits, presumably you should be
careful to not edit any files larger than the free memory on your system.

You could make the command set an at job instead of calling shutdown
directly, but that's a bit hackish. There must be a way to make the
command run in the background, but I don't know the trick offhand.

Why would cfagent think the date is the epoch, even though the system
clearly has the right date?
And why would such an anomaly cause cfagent to fail to run?
Note this is cfengine 2.1.21...

Where did the cfengine 2 documentation go? The link on the resources
page says "all editions" but points to only Cf3 documentation. For us
slow adopters, we still need the Cf2 docs!!

That's the whole problem. If you can't rename across filesystems then
you can't use that feature to create backups.

There used to be a Cf2 regex tester on cfengine.org, as referenced here:
http://cfwiki.org/cfwiki/index.php/Wishlist#RegExp_Testing
But it seems to have vanished. Could it be restored? It would be handy
to have around for those of us (cough) still using Cfengine 2...

I think the value in this case is less in the simplicity of the code,
and more in the fact that it allows you to fully document the
intentions/behavior of a given promise without having to resort to 3rd
party code, i.e. the promise becomes self-documenting.

cf.sitecontrol comes *after* cf.control so that some global macros can

own cfengine's awareness of certain
services. That way, we can keep cfengine enabled, but have it ignore
certain "chunks" of policy to allow for some degree of local autonomy on
one-off boxes.

The documentation seems to suggest that's just for recursion (i.e.
recurse into directories pointed to by symlinks), not copying of

o:
./
./script.v6.1
./script.v6.2
./script.v7.0
./script.current -> script.v7.0
This script needs to be copied to the local filesystem, so I'm using a
copy: statement that copies "script.current" to a destination in the
local filesystem. But it's literally copying the symlink,
Simply putting a shebang on the file doesn't fix the issue of importing
a "cf.common" of some sort *before* running the script in question. The
quickie bash script that Brendan suggests addresses that problem.
