Bug#973688: console-setup.service fails only at the first boot

[Ryutaroh Matsumoto <ryutaroh@ict.e.titech.ac.jp>]

Package: console-setup
Version: 1.198
Severity: minor

Dear Maintainer,

I am using Debian Sid Arm64 in QEMU emulator.
console-setup.service fails only at the first boot,
and runs well after poweroff and reboot the emulator.
journalctl -u console-setup.service shows the following.
The line /bin/setupcon: 870: cannot open /tmp/tmpkbd.klAKsq: No such file
seems mysterious...
