One issue is what permissions to apply to newly created files when none are
specified? Historically, Puppet has always copied the permissions from the
file source to the newly created one. However, this causes problems on
Windows agents due to the way that Puppet emulates POSIX permissions. We
break NTFS access control inheritance to ensure the effective permissions
are not greater than what Puppet has granted. It also causes problems on
*nix agents, when the files' source is remote and uid/gids are not
A second, but related issue, is that Puppet applies the same
copy-permissions logic to files that already exist. This goes against what
jcbollinger said, "unmanaged resources and resource properties should not
be modified by Puppet", and what Nigel said, "A core principle of Puppet
is that you can choose to only manage the attributes of a resource that you
care about, and can leave the rest unmanaged." However, this "bug" has
been around so long, at least 0.24.8, that we can't change behaviors in a
Patrick and I talked about this and would like to propose adding a file
parameter, something like `use_source_permissions`. If true and permissions
are unspecified, Puppet would continue copying source permissions as it
does today, for both newly created and existing files. This would be the
If false and permission are unspecified, Puppet would never copy them from
the source. Instead the permission defaults for newly created files would
be based on the user that Puppet is running as. And the permissions for
existing files would be unmodified.
Doing so would provide a mechanism for resolving both #5240 and #18931.
