Subject: The symlink is still there, the target is missing

Date: Tue, 23 Jan 2018 22:04:55 +0200

Control: retitle -1 dash upgrade fails, resulting in /bin/sh linking to nonexisting dash binary

The symlink is actually still there, /bin/dash is missing at that point:

$ ls -la /bin/sh /bin/dash
ls: cannot access '/bin/dash': No such file or directory
lrwxrwxrwx 1 root root 4 Jan 23 19:53 /bin/sh -> dash
$
