 Currently, if you're using pkgsrc framework, it is expected, that your
 binary tools are consistent with framework settings. In fact, if you use
 the framework correctly, the latter defines everything (we even support
 installation of newer pkg_install on NetBSD, if the base one is too old).
 I don't think that it is practical to implement support for pkg_install
 being hostile to pkgsrc, that's why (one of reasons) I argue that this
 is not a bug.

 If you delete /usr/pkg, you should delete pkgdb as well. You're expected
 to reconfigure your system startup scripts yourself too, unless they are
 tolerant to executables that disappear with removal of /usr/pkg.
 It may be that you need to remove other binaries that reference libraries
 from /usr/pkg/lib too. There's a lot of what you may need to do when you
 remove anything from your system in addition to removal of /usr/pkg.

 That's possible too.

 This works just fine, if you don't do anything unexpected.

 I don't think that this isn't practical since _PKGDB_DIR is set correctly
 when you run bootstrap script. If you don't, then you're basically on
 your own. And here you add another fork+exec just to accomodate to your
 rather peculiar goals.
