I already reported the issue in 2017 (4 years ago!), but nothing has been done yet. See * Initial message: https://lists.debian.org/debian-user/2017/04/msg00789.htmlAnd the comment from 2017 still holds true: https://lists.debian.org/debian-user/2017/04/msg00790.html " See the comment in there: # These rules will create symlinks for CD/DVD drives, to help old # programs which are unable to automatically discover the devices. # The first detected device gets the symlink, but this is not stable across # reboots. So, yes, what you see can happen depending on the order devices are discovered. " The kernel hasn't changed. It still probes devices asynchronously. There is not much we can do about that.The comment says: "The first detected device gets the symlink". If this were true, all symlinks would be the same (even though this would not be stable), which is not the case. BTW, aren't the devices numbered 0, 1, etc. in the order they are detected, so that one would expect always sr0 here?
It appears you do not believe what I said. Feel free to propose a patch.
