No. ANY path that would look akin to this
It's empty. Seems like a lot of users have left paths (which were unused by them) blank instead of hitting "Remove"
<6.12.8 docker itself ignored it. 6.12.8+ Docker returns an error (IMO rightfully so).
Trouble is that if you've done that without this patch on 6.12.8 when you simply update the container it will return an error, become an orphan, and require a reinstall from Apps, Previous Apps and you to find the empty path and remove it. I figured the patch would save everyone a ton of hair by ignoring empty paths when the docker run command gets created.
As said, it's not a bug in the OS. I'm just making things work the way they used to for this one thing. I figured that if one of the LT devs winds up asking me WTF happened here (and some users before the patch), it would wind up becoming a nightmare and a one line change solves it.
