This may not fit your requirements but a slightly safer alternative
might be set your old users' shells to /bin/false and null out their
password, rather than delete them. A small added bonus is if your UIDs
are never reused then all your UIDs will resolve to user accounts, which
can be helpful later down the track if you want to know who owned which
file, rather than it just be an unresolved UID number.

Realizing doesn't allow overrides. To remove the user:

This may mean you need to use inheritence for the class the user is
defined in, creating a child class for the nodes you want to remove him on.
Oha,
that sounds like putting a lot of thinking building the configuration
system.
Indeed, yes. It is a complex task, and thinking is required.
Note, by the way, that virtualization really doesn't have much to do with
this particular issue. There are basically two ways to remove users with
Puppet:
1. The fairly safe way: manage the user, setting ensure => absent. That
'ensure' parameters could be set on the actual resource declaration,
perhaps conditionally, or it could be overridden later, such as via a
collection.
ok,
2. The simple, but rather dangerous, way: use the 'resources'
metaresource to declare that all unmanaged, non-system user accounts should
be purged from the system. This has the potential to bite you -- hard --
but it has the advantage that all you have to do is stop realizing a user
or else not declare him at all to have him removed.
I confess I like that idea.
Note that even approach (1) I designate only "fairly" safe. It is that
because you explicitly specify all user removals, but nothing can change
the fact that removing users is inherently risky.
thx a lot
