    If you have apt-file on your system, you can check what packages would place manpages in section 9:

    $ apt-file search /usr/share/man/man9 |
    awk -F: '{seen[$1]++} END{for(p in seen) print p ": " seen[p]}'
open-vm-tools: 1
freebsd-manpages: 1934
librheolef-dev: 1
ax25-tools: 3

    By far the majority are from the freebsd-manpages package, whose description is

    Description: Manual pages for a GNU/kFreeBSD system
 This package contains a selection of manual pages from FreeBSD that are useful on a GNU/kFreeBSD system:
  2 = System calls (functions provided by the kernel)
  4 = Special files (usually found in /dev)
  9 = Kernel routines

    So, unless you are running a GNU/kFreeBSD port, you should not expect to see any kernel routine manpages in Section 9.
