When run without -d, onie-bisdn-upgrade offers this warning:
Upgrading BISDN Linux to install-source: <URL> using Client-IP-cfg: dhcp! Please confirm system reboot: [y/N]
The reboot should be rather obvious when installing a new operating system. However, upgrading BISDN Linux will preserve files only if they are listed in /var/lib/opkg/info/*.conffiles or /etc/default/{system,user}-backup.txt. [1]
This is what onie-bisdn-upgrade should warn about.
