Without further ado, the following was found: Issue: libmount → B<libmount> "Since version 2.35 B<umount> command does not exit when user permissions are " "inadequate by internal libmount security rules. It drops suid permissions " "and continue as regular non-root user. This can be used to support use-cases " "where root permissions are not necessary (e.g., fuse filesystems, user " "namespaces, etc)."
