~/Library/Containers/com.docker.docker/Data/database has broken .git directory

[lexicalunit]

Expected behavior

We expect ~/Library/Containers/com.docker.docker/Data/database to be a valid repository with a valid .git directory. You should be able to enter that directory and run git commands such as git status.

Actual behavior

$ cd ~/Library/Containers/com.docker.docker/Data/database
$ ls -la .git
total 8.0K
drwxr-xr-x 5 me staff 160 Feb 19 12:49 ./

Steps to reproduce the behavior

1. Install Docker for Mac.
2. cd to the mentioned directory.
3. Try to run any git command, such as git status. It will fail because the .git directory is not valid.

Hello,

Since 17.12, we are no longer using the git-ish DB. We just forget to clean it up during the update.

[lexicalunit]

@pgayvallet does this mean that modifying a file in this directory no longer has any real effect? In my case I'm looking at the file com.docker.driver.amd64-linux/disk/on-flush and putting the text os into it. Is that just not used anymore or is it just that it's no longer a git repo?

@pgayvallet I need to increase the number of allowed file descriptors. According to #1009 (comment), I need to edit a file in this Git repository, but as you point out it no longer exists. What's the replacement?
