 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...
