Pandawan fails with errors in `/proc/sys`

[reteps]

The end of my bootup process looks like this:

init started: BusyBox v1.19.4 (2024-06-06 11:43:25 Europe)
/etc/rc.d/rc.sysinit: line 6: can't create /proc/sys/kernel/panic: nonexistent directory

Segmentation fault

I tried running Pandawan with the qemu arguments firmadyne.procfs=1 and firmadyne.procfs=0, and both gave me this identical error trace. I was wondering if this was a known issue for certain firmwares.

Does this also occur during the network configuration phase? In that case Pandawan uses stock QEMU to emulate the firmware and deduce its networking (like Firmadyne and FirmAE). Check the qemu.initial.serial.log file if the emulation progrssed beyond this point. If yes then either its (Py)PANDA's fault or Pandawan's fault. Try Pandawan's emulation without any of Pandawan's plugins enabled (i.e., -p "") and see if this occurs again. If it does, then there might be an issue with PANDA.
