Manage user home dirs

Patch to add 'managehome' attribute to users

I agree that this functionality is useful and important.

The patch could be better in a couple of ways. First, the comment no longer has to be quoted because Puppet now does a direct exec instead of using a subshell -- the comment above the quoting code is wrong, which is my fault.

Second, I think that the 'ensure' state should be extended to support two types of deletion -- the current "absent", and a new "purged". Plain "absent" should just remove the user, and "purged" should delete the home directory.

I'm fine accepting it as it is for now (other than the quoting), but when resources have such a big impact on other resources, we want to be pretty careful about destroying information.

The quoting is unnecessary - I forgot that no shell is involved at exec.

How could one label by 'ensure' that the user account should be created together with the home directory? Just to find a pair to 'purged' and I'll submit a new patch.

For creating the user, using a parameter is the right option, I think, but 'managehome => true' does not at all imply that a user's home directory will be recursively deleted if the user is deleted, so I think it's appropriate to have an extra 'ensure' value to clearly indicate that deletion is happening.

Basically, ensure => purge should behave almost the same as ensure => absent, except that it should add the "-r" to userdel.

Hm, is this then what you want? Seems to simple, but might work?

A small modification of the original patch

This patch is what I meant, sorry :|

Applied most of these patches, with significant modifications, in [2238]. Purging is still not yet supported.
