    So things regarding this Linux capabilities message are even murkier than
    I'd suspected.

    First, some Linux kernels were released with caps version 2, and the
    warning in the system log being emitted by the kernel if the caps version
    macro didn't match the kernel version macro. Then, later, some of the
    Linux kernels were changed to use a caps version 3, because version 2
    turned out to source backward-incompatible. The only difference with
    version 3 is that it avoids a second system log warning (which is emitted
    by the kernel if caps version 2 are used).

    Second, it is not clear whether Linux distributions will provide the
    necessary matching libcap library a) as a separate library named
    "libcap2", or b) simply update any existing "libcap" library, or c) simply
    update the libc library with the proper symbols. I suspect the answer is
    that all three approaches will be seen.

    I've opened a bug to update proftpd's configure script to look for libcap2
    libraries first; this should _hopefully_ fix some instances of the
    warning:

    But please keep in mind that the message which appears is a warning only;
    it does not necessarily indicate any "security" issues.
