Dockerfile difference between revision releases #884
Description
The debian->oracle image switch omits the /entrypoint.sh symlink
The applicable line from a debian Dockerfile is the following:
https://github.com/docker-library/mysql/blob/master/5.7/Dockerfile.debian#L96
While that symlink is itself a backwards compat thing, I don't think its the sort of thing which should be removed from what is otherwise just a revision update from 5.7.37 to 5.7.38 (for tags like :latest I agree that all bets are off, but I think there should be a degree of consistency between releases in the same major.minor series)
If you were looking to keep the oracle Dockerfiles clean but still have those be the new foundation, perhaps until a new release series comes to exist, the former debian defaulted tags such as :5.7 could build FROM mysql:5.7-oracle, simply adding things like the entrypoint symlink, a symlink for the config dir changes which were mentioned in other issues. It might also allow a more explicit means to warn of deprecated changes in that image series
