    [$] Practical uses for a null filesystem

    Thu, 12 Mar 2026 14:58:09 +0000

    Description:
    One of the first changes merged for the upcoming 7.0 release was nullfs ,
    an empty filesystem that cannot actually contain any files. One might logically wonder why the kernel would need such a thing. It turns out,
    though, that there are places where a null filesystem can come in handy.
    For 7.0, nullfs will be used to make life a bit easier for init programs; future releases will likely use nullfs to increase the isolation
    of kernel threads from the init process.
