Here's something I prepared earlier;)
Don't know why it got stuck, quite possibly I realized some fatal flaw that I
can't remember anymore...
Seems to work though, so getting this out for review and testing.
The code looks good to me.
I have a small test program which writes 100MB to a tmpfile and then checks its contents:
https://github.com/georgmu/overlaytest
I have tested manual overlayfs creation (make overlaytest) and docker (make dockertest).
For docker: `docker info | grep "Storage Driver"` should be "overlay2".
I may enhance the test to create multiple tmpfiles in parallel.
Thank you very much for the code. I would add my tested-by.
Best regards,
Georg
