If the global scope git config (~/gitconfig) is an empty file, it cannot be attached to a dev container.

[tun24]

Attachment failed when starting devcontainer after removing all globally scoped git settings.
This only occurs when the git config file (~/.gitconfig) is an empty file.
It does not occur if there is no file or if the file is more than 1 byte.

• VSCode Version:1.91.1
• Local OS Version: Windows 11 Pro 23H2
• Remote OS Version: Ubuntu 22.04.3 LTS(WSL)
• Remote Extension/Connection Type: Containers

Steps to Reproduce:

1. Create devcontainer.json
   https://code.visualstudio.com/docs/devcontainers/create-dev-container#_create-a-devcontainerjson-file
2. Create empty git config file
   mv ~/.gitconfg{,.back.devcontainer}
   touch ~/.gitconfig
3. Open devcontainer in VSCode

result:

Does this issue occur when you try this locally?: Yee
Does this issue occur when you try this locally and all extensions are disabled?: Yes

Unfortunately I cannot reproduce it. Could you append your devcontainer.json?

[tun24]

Here is the devcontainer.json I used for verification.
devcontainer.json

Full logs of success and failure will also be included.
We reinstalled Ubuntu 24.04 on WSL and installed Docker Engine to verify.

• On success: ~/.gitconfig is not an empty file
  success.log

• On failure: ~/.gitconfig is an empty file
  failed.log
