There are no hashes in my example. In particular, resource declarations
are not hashes, and do not (generally) contain hashes. The only hashes
discussed in this thread so far are your $fs_hash and its contents.
You can avoid using 'require' by using chaining arrows instead. For
example,
base::fsdef { '/dev/sdb1': mountpoint => '/data/01' }
-> base::fsdef { '/dev/sdc1': mountpoint => '/data/02' }
-> base::fsdef { '/dev/sdd1': mountpoint => '/data/03' }
-> base::fsdef { '/dev/sde1': mountpoint => '/data/04' }
-> base::fsdef { '/dev/sdf1': mountpoint => '/data/05' }
-> base::fsdef { '/dev/sdg1': mountpoint => '/data/06' }
-> base::fsdef { '/dev/sdh1': mountpoint => '/data/07' }
-> base::fsdef { '/dev/sdi1': mountpoint => '/data/08' }
-> base::fsdef { '/dev/sdj1': mountpoint => '/data/09' }
-> base::fsdef { '/dev/sdk1': mountpoint => '/data/10' }
That is 100% equivalent to the alternative using the 'require'
metaparameter. You can even mix and match. You can also add relationships
after the fact by applying chaining arrows to resource references:
file { '/tmp/after': ensure => 'file' }
file { '/tmp/before': ensure => 'file' }
# this may appear anywhere in the manifest set:
File['/tmp/before'] -> File['/tmp/after']
If your point in wanting to avoid 'require' is that you want an attempt to
be made to perform each mount, even if previously-listed ones fail, then we
come back around to my previous opening question: why? Why does the order
in which the mounts are applied matter?
Anyway, the Puppet documentation contains a full description of factors
affecting resource application order
<https://docs.puppetlabs.com/learning/ordering.html>. You should read and
understand the whole thing.
I note in advance that you will find among the docs reference to Puppet's
'ordering' configuration parameter. You may like the sound of it, but you
shouldn't. If you have bona fide requirements for the order in which
resources are applied, then you should declare those requirements
explicitly in your manifests (as the docs also say).
