comment What filesystems preferentially reuse blocks from deleted files?

comment How to grep a specific line _and_ the first line of a file?
I don't like this solution, primarily because the situation could change between the first and second ps aux call... And if you just want that static first line, why not echo it manually?

I'm fairly sure no. A mount point isn't a symlink.
