Just a heads up.
This patch causes Konsole and tmux startup failures on my machine, e.g.:
konsole(364)/kdecore (KPty/K3Process) KPty::open: Can't open a pseudo teletype
To fix this issue I had to remount devpts with gid=5:
mount -o remount,gid=5 /dev/pts/
My original fstab had this entry:
devpts /dev/pts devpts rw,relatime,mode=600 0 0
