Critical for offline installs/upgrades, which can't access internet directly, or at the moment of the upgrade.
Version checking and downloading the update information works, but actual package download doesn't. After reboot, the system enters in an endless bootloop at startup "An error occurred on pkg execution (rc = 70)"

Can be solved by manually editing pkg.conf and modifiying the pkg_env sections as follows:

pkg_env: {
http_proxy=http://proxy:port
https_proxy=http://proxy:port
HTTP_PROXY=http://proxy:port
HTTPS_PROXY=http://proxy:port
}

Solution would be pkg.conf to be automatically populated with correct proxy info when proxy is configured from the Web interface.
