There are no cross-platform useradd tools that we can use, and there is
no deep yearning within me to write wrappers around each platform's
native user management tools, so if a NetBSD-compatible user(8) and
group(8) don't exist, then that platform should default to
PKG_CREATE_USERGROUP=no so that the admin is prompted at pre-install
time to create the users/groups manually. On my own NetBSD systems, I
default to PKG_CREATE_USERGROUP=no anyway just so I can more precisely
control the uids and gids allocated on my systems.
