Morning all! I would like to propose adding a flag to the syscall underlying mount(2) that disables symlink expansion. The motivating use case for this is as follows: I am trying to set up a netns namespace that requires a specific DNS setup, to this end, I am creating a mount namespace and replacing /etc/resolve.conf. Unfortunately, resolv.conf is a symlink provided by systemd-resolved. Bind mounting over said file with my replacement is impossible: With `-c` option, the `mount` command actually targets `/etc/resolv.conf` instead of the file it's pointing to, but the kernel expands it internally and seems to mount over the file being pointed to. I highly similar use cases exist. I have tried the nosymfollow option, which did not work. I think it affects only how symlinks are handled once the fs is mounted. Best, Karolin Varner
