Dear Maintainer, I have Debian 9 where I do some software development of software in Rust language. I have Debian 10 where I do some other things. I change and compiled a Rust program from Debian 10 into Debian 9, using a terminal as super user. It was a disaster when I entered in debian 10. The file system became unstable. I restarted the Debian 9, and it didn't restart. I needed to enter in rescue mode to check and to recover the file system. I typed "command fsck /dev/sda5" in an minimal OS. The file system was recovered successfully.
