    There are two reasons not to do it that way:

    - atomicity
    - backwards compatibility

    Of these, I would argue the former is the most important.

    Additionally, I don't think sysfs has the ability to present different
    structures on a per-process basis; keep in mind this isn't really
    /proc/mounts, but really /proc/<pid>/mounts.
