  # ### lx-symbols after continue
  #
  # lx symbols must be run after continue.
  #
  # running it immediately after the connect on the bootloader leads to failure,
  # likely because kernel structure on which it depends are not yet available.
  #
  # With this setup, continue runs, and lx-symbols only runs when a break happens,
  # either by hitting the breakpoint, or by entering Ctrl + C.
  #
  # Sure, if the user sets a break on a raw address of the bootloader,
  # problems will still arise, but let's think about that some other time.
  #
  # ### lx-symbols autoload
  #
  # The lx-symbols commands gets loaded through the file vmlinux-gdb.py
  # which gets put on the kernel build root when python debugging scripts are enabled.
