WARNING: daemon is not using the default seccomp profile

Expected Behavior

os.EOL should return 0a (\n) or LF, matching the operating system line feed for Debian

Current Behavior

os.EOL returns 0d 0a (\r\n) or CRLF

Possible Solution

I am unsure. I have not found the root cause.

Steps to Reproduce

On any macOS or linux system running docker:

docker run --rm -it node:18 -p 'require("os").EOL' | hexdump -c
node -p 'require("os").EOL' | hexdump -c

0000000  \r  \n  \r  \n (wrong)
0000004
0000000  \n  \n (correct)
0000002

Additional Information

This is causing errors with yarn@3 yarn.lock file. When ran with the --immutable tag, yarn will attempt to re-write the yarn.lock file with CRLF line endings, causing any build to fail. This was changed in this issue: https://github.com/yarnpkg/yarn/issues/1061
