Arch Linux

This is probably an upstream issue, but it doesn't look like it's maintained anymore:

https://lists.nongnu.org/archive/html/xbindkeys-devel/

There's a fork, but I'm not sure if they want to go on, and that might be kind of a spin-off:

https://github.com/sharmanr/xbindkeys

Steps to reproduce:

/usr/local/bin/xbindkeys.sh:

#!/bin/sh -eu
stdbuf -o0 xbindkeys -n -v > /tmp/xbindkeys.log 2>&1

$ pkill -HUP xbindkeys

then try to press any keybindings.

$ cat /tmp/xbindkeys.log

I launched urxvt, sent HUP, after which the keybindings stopped working.

I'm running awesome + lightdm.
