Hello!
Imagine that I have the following in my puppet manifest:
file { ''/etc/master.passwd'':
mode => 0600,
source => ''puppet:///modules/test/etc/master.passwd'',
}
When agent notices that master.passwd should be refreshed, how exactly
does copy process happen?
Is it atomic (e.g. fetch to some temp filename on local filesystem and
then rename)?
Or it will fetch the file over the net to the destination name (and so
there is some short period of time when
target file is in inconsistent state)?
Thanks!

Imagine now that I want to update several config files related to each other. It would be error to update some of them and leave others in older state. So I want either all of them to be refreshed, or, if disk is full, to keep all them untouched.

On the other hand, you should already be monitoring for full or filling disks, and have alerting or remediative action available.> -- > You received this message because you are subscribed to the Google Groups "Puppet Users" group. > To post to this group, send email to puppet-users@googlegroups.com. > To unsubscribe from this group, send email to puppet-users+unsubscribe@googlegroups.com. > For more options, visit this group at http://groups.google.com/group/puppet-users?hl=en. > >-- You received this message because you are subscribed to the Google Groups "Puppet Users" group.

This works best if the files change rarely and are not customized on a per-machine basis, but in principle it could be done dynamically. If a full disk is a significant concern, however, and not just an example, then please do recognize that the package approach has more overhead on the client than some alternatives.
