To handle this, I have multiple wpa_supplicant config files for each of the APs, and I use logical interfaces in /etc/network/interfaces to select the appropriate config file. For example: iface public inet manual wpa-conf /etc/wpa_supplicant/public.conf iface private inet manual wpa-conf /etc/wpa_supplicant/private.conf To select the appropriate AP, I simply run `ifup wlan0=public` or `ifup wlan0=private`. This part works fine. However, I would like to change the "wpa-conf" lines in the above example to use "wpa-roam" instead, so I can also handle roaming in conjunction with multiple wpa_supplicant config files. Unfortunately this doesn't work. When the "master" interface is already using a logical interface in /etc/network/interfaces, wpa-roam fails to load the logical interface specified by id_str. The problem is that the ifup() function in functions.sh runs `grep -q "^$WPA_IFACE=$WPA_IFACE" "$IFSTATE_FILE"` to determine if the interface is already up, then runs /sbin/ifup either with or without ' --force' depending on whether the interface is "up". If the "master" interface is defined in /etc/network/interfaces as a logical interface rather than a physical interface, then grep will not match, '--force' will not be used, and /sbin/ifup will fail because the interface is already configured and '--force' was not used. The attached patch fixes this issue by running `ifquery` to determine whether the physical interface is currently configured as a wpasupplicant "master" interface and needs the '--force' argument to /sbin/ifup.
