      Since nano runs with the partition in read-only mode, I thought crash dumps got written to a 'crash dump only' partition. I see there are indeed two 1.8gb partitions and one 50mb partition, all listed as freebsd (by "gparted show"). I know the two 1.8gb's are the active partition and the 'boot failure/last known good' partition. Since this is nano, I assume the 50mb isn't a swap partition.

      Is the 50mb actually for crash dumps or …?

      I did a normal install once (aka, full instead of nano) and after crashes I noticed a banner in the webcfg mentioning the existance of a crash dump. Since I don't get those with nano, I'm wondering if these are indeed not saved on nano.

      So, long story short:
        Are crash dumps saved anywhere on nano?
        If yes, how would I access them?
        If not, is saving the serial output the only way to see any crash info on nano?

      Thanks!

        There's no crash dump partition anywhere on nanobsd. That 50MB /cf is for configuration files, not for any dumps.

          No they are not. Saving crash dumps requires swap space and NanoBSD doesn't have swap space (to keep disk writes low).

          Yes that's the only way.
