Tests

  • Finish an MTD partition layout parser
  • Finish a free parser
  • Finish a df parser
  • Finish a kernel log regex scanner for the machine type
  • Figure out interesting OS oper state tests, e.g. "in U-Boot", "in userspace", "kernel panicked"
  • Test primary/secondary determination using bootconfig binary data decoding
  • Write a connection URI parser and test it for serial and ssh, test unsupported types

Partition layout compatibility

  • Encode a partition layout decoder and map it over a known layout
  • Have a mechanism to perform migrations (return ENOSUPPORTED for now, all the time)

Toplevel compatibility

  • Encode a toplevel decoder and map it over a known device type
  • Verify compatibility

Misc

  • Retrieve stores paths for a specific image type
  • Compute delta
  • Test for delta computations
  • "Does it fit in the target" tests
  • Copy closure primitive (in dry run, this should NEVER RUN for real)

Next steps:

preinit project (ZeroPulse)

  • Fix the kernel command line parameters passed from U-Boot.
  • Reuse the previous code library.
  • When booting an A/B system, use the proper kernel command line argument to open the right devices.
  • Support complicated layouts implying overlays and userdata.
  • When everything fails, fallback to a failsafe initialization with a predefined failsafe script.

Advanced U-Boot control (AbyssCommand)

  • Support for MRD modification (decode it, modify a single byte of it, etc.)
  • Boot into TFTP (assumes serial connection type)
  • Recover (assumes serial connection type)
  • Listen for netconsole messages

Initialization

  • Bootstrap: try to detect if the target system is running a stock OS and will send the initial installation payload

Write an agent component (advanced)

  • If the agent is supported, SSH can use it or agent connection can happen directly.

Maybe a rename of the whole tool to aeroswitch because I can do it.
