Description Robert Forsman 2017-12-04 20:32:59 UTC 
In /usr/share/bash-completion/completions/fsck from sys-apps/util-linux-2.30.2 the final COMPREPLY= uses $(find -L /dev/ -type b 2> /dev/null) .

On my computer this ended up diving into /dev/fd/3/.wine/dosdevices/z: which is a symlink to / (the root) and things quickly got stupid.  The shell prompt became non-interactive.

The COMPREPLY used in util-linux-2.28.2 uses $(lsblk -pnro name) which does not have this problem.

You probably want to adjust the completion function back to lsblk, or at least something that doesn't render the shell noninteractive.
