Comment 4 for bug 1651818

Well of course it is not the default unlocking mechanism.
In my setup cryptroot-unlock is used to unlock remotely over dropbear.
Most probably the regex can adapted. But I have no experience with that.

When I encountered the issue I tested the script with standard busybox and it
worked. Then I compared the config of the two packages and found the two parameters
to be essential. It was the easiest way for me.
Of course I did not check for other side effects of the change.

A second command is not working with the initramfs busybox. It's "grep -Ez".
The z option is not present.
