I've used ifscheme happily for a long time and on numerous
computers. Just recently I installed "unstable" from scratch on a Dell
XPS 13 9343. And now ifscheme doesn't work anymore.
This if the configuration I have in /etc/network/interfaces:
mapping wlp2s0
script ifscheme-mapping
iface wlp2s0-home inet dhcp
wpa-ssid MyWiFi
wpa-psk MyPSK
dns-nameservers 208.67.222.222 208.67.220.220
iface wlp2s0-mobile inet dhcp
wpa-ssid PhoneWiFi
wpa-psk PhonePSK
I can verify that ifscheme is parsing my config correctly:
$ sudo ifscheme --list
home
mobile
But when I try to select a network and bring up the interface, I get
the error "unknown interface":
$ sudo ifscheme home
Scheme changed to home.
$ sudo ifup -v wlp2s0
ifup: running mapping script ifscheme-mapping on wlp2s0
ifup: ignoring unknown interface wlp2s0=wlp2s0
I know this isn't the correct way to use it, but just in case I also
tried bringing up the interface with the ifscheme suffix:
$ sudo ifup -v wlp2s0-home
ifup: configuring interface wlp2s0-home=wlp2s0-home (inet)

wpa_supplicant: /sbin/wpa_supplicant -s -B -P
/run/wpa_supplicant.wlp2s0-home.pid -i wlp2s0-home -D nl80211,wext -C
/run/wpa_supplicant

wpa_supplicant: /sbin/wpa_supplicant daemon failed to start
run-parts: /etc/network/if-pre-up.d/wpasupplicant exited with return code 1
ifup: failed to bring up wlp2s0-home
I guess this would happen even if I didn't have the ifscheme mapping
configured; it's effectively assuming that an interface called
literally wlp2s0-home exists.
I'm wondering if this might have something to do with the new(-ish)
"predictable" network interface names. The reason I considered this is
because my old laptop had a WiFi interface called wlan0 under the old
scheme (as well as eth0). That machine was also Debian "unstable" but
was originally installed c.2013 and just continuously upgraded.
