----------------------------------------
First of all let me say it fails in some situations, not always. Here is the
code which I have:
class filesystem {
File {
ensure => directory,
mode => '0755',
owner => 'root',
group => 'root',
}
# Recursive function creates chain of objects
define make_dir($owner=undef, $group=undef, $mode=undef) {
file { $name:
ensure => directory,
mode => $mode,
owner => $owner,
group => $group,
}
# Take parent directory name
$parent = regsubst($name, '(.+)(/[^/]+)$', '\1')
# Recursive call if object does not exist
if ( $parent != "" and ! defined(File["$parent"])) {
make_dir { $parent:
mode => $mode,
owner => $owner,
group => $group,
}
File["$parent"] -> File["$name"]
}
}
}
class filesystem::common inherits filesystem {
make_dir { [
'/usr/local/bin',
'/usr/local/etc',
]:
}
}
So, when I do have two directories with the same parent directory, the class
will fail:
Mogul:manifests user$ minicatv example.com filesystem::common
notice: looking up example.com...
err: Duplicate declaration: Filesystem::Make_dir[/usr/local] is already
declared in file /home/user/Dvl/my_test/modules/filesystem/manifests/init.pp at
line 63; cannot redeclare at
/home/user/Dvl/my_test/modules/filesystem/manifests/init.pp:63 on node
example.com
err: Try 'puppet help minicat compile' for usage
There is no issue with /usr but with the longest common part of items. The
workaround is to add the parent directory into the list like that:
/usr/local
/usr/local/bin
/usr/local/etc
That case all directory objects, including /usr, will be created with no
errors. It is not obvious to me where and why puppet fails and I only assuming
it could be a bug.
