pkg(7) ignored "PACKAGESITE" environment variable

[epopen]

Hi All

I'm trying to use pkg(7) with local repository.
And need change repository dynamically working for jail(7)

I had saw in pkg(7) section CONFIGURATION

url           Refer to    PACKAGESITE in "ENVIRONMENT"

My work fine configure of repository: /usr/local/etc/pkg/repos/barfoo.conf

BARFOO_PKG: {                                                                                                                                                                                              
    url: "file://[WORK_FINE_REPOS]",
    enabled: yes
}

Disabled original FreeBSD repository /usr/local/etc/pkg/repos/FreeBSD.conf

FreeBSD: {
    enabled: no
}

FreeBSD-kmods: {
    enabled: no
}

And reference other thread about PACKAGESITE, my test procedure...

1. Modified /usr/local/etc/pkg/repos/barfoo.conf
   

   BARFOO_PKG: {                                                                                                                                                                                              
       url: "file://[NOT_EXIST_REPOS]",
       enabled: yes
   }

2. Set PACKAGESITE environment variable with work fine repository
   setenv PACKAGESITE "file://[WORK_FINE_REPOS]"
3. Execute pkg(7)
   # /usr/local/sbin/pkg --debug install --dry-run zip
4. Result:

pkg(7) always using url of /usr/local/etc/pkg/repos/barfoo.conf, ignored my wishing PACKAGESITE
