-How to create vmcores for tests
-===============================
-
-1. Boot a FreeBSD VM with as little memory as possible and create a core dump
-   per `FreeBSD Handbook Kernel Debugging Chapter`_.  Note that you may need to
-   reboot with more memory after the kernel panic as otherwise savecore(8) may
-   fail.
-
-   For instance, I was able to boot FreeBSD and qemu-system-x86_64 with 128 MiB
-   RAM but had to increase it to 256 MiB for the boot after kernel panic.
-
-2. Transfer the kernel image (``/boot/kernel/kernel``) and vmcore
-   (``/var/crash/vmcore.latest``) from the VM.
-
-3. Patch libfbsdvmcore using ``libfbsdvmcore-print-offsets.patch`` and build
-   LLDB against the patched library.
-
-4. Do a test run of ``test.script`` in LLDB against the kernel + vmcore::
-
-    lldb -b -s test.script --core /path/to/core /path/to/kernel
-
-   If everything works fine, the LLDB output should be interspersed with
-   ``%RD`` lines.
-
-5. Use the ``copy-sparse.py`` tool to create a sparse version of the vmcore::
-
-       lldb -b -s test.script --core /path/to/core /path/to/kernel |
-           grep '^% RD' | python copy-sparse.py /path/to/core vmcore.sparse
-
-6. Compress the sparse vmcore file using ``bzip2``::
-
-       bzip2 -9 vmcore.sparse
-
-
-.. _FreeBSD Handbook Kernel Debugging Chapter:
-   https://docs.freebsd.org/en/books/developers-handbook/kerneldebug/
