Simple answer - no. Dependencies can only be between objects in
0.24.x...
I believe (but haven't seen for myself yet) that there are changes to
this coming as its a frequently requested feature...
I used to think it was a good idea, then I sat and thought about it
for a while and now I don't actually want it... One issue of enabling
this will be potential for a more complex dependency circle. Eg:
class foo {
file { "/tmp/foo": require => File["/tmp/foo2"] }
}
class foo2 {
require => Class['foo']
file { "/tmp/foo2": ensure => present }
}
This scenario would create a (possibly hard to see) circular
dependency...
If you have a lot of objects that have a common dependency - use
defines. Common one I had was lots of users requiring a common
resource:
user { "foo": uid => 1000, require => File["/home"] }
This type of thing can be annoying to specify require => File["/home"]
for 1000's of users... Easy way to deal with it:
define luser ($uid) {
user { "$title":
uid => $uid,
require => File["/home"]
}
}
Then use: luser { "foo": uid => 1000 }
Another way is to use the Type defaults to specify this sort of thing.
For example:
User {
require => File["/home"]
}
This makes all users require File["/home"]. This is a bit more
restrictive (overwriting it can in some circumstances be a pain) so it
may not work in all cases...
Specifying each individual dependencies can seem like a pain in the
ass, but your resulting config will be better for it - Puppet will be
more effective when you get it right...
