This still appears to be a problem.

In /var/db/pkg.refcount I've got no "users" or "groups" directories
before the install.  After the install there's:

   bigkev 116> find /var/db/pkg.refcount/[gu]*
   /var/db/pkg.refcount/groups
   /var/db/pkg.refcount/groups/operator
   /var/db/pkg.refcount/groups/operator/+PREEXISTING
   /var/db/pkg.refcount/groups/operator/amanda-common-2.4.4p4nb4
   /var/db/pkg.refcount/users
   /var/db/pkg.refcount/users/backup
   /var/db/pkg.refcount/users/backup/+PREEXISTING
   /var/db/pkg.refcount/users/backup/amanda-common-2.4.4p4nb4
   bigkev 117> find /var/db/pkg.refcount/[gu]* -name +PRE\* | xargs cat
   amanda-common-2.4.4p4nb4
   amanda-common-2.4.4p4nb4

It looks like the refcounting doesn't include existing "system"
accounts.  I'm also not sure how it would do that, making a distinction
between accounts that were originally created by pkgsrc and pre-existing
accounts on the system.  It'd be nice to think of a way that doesn't
need a hard-coded list of OS-dependant system users and groups...
