Crash dumps on embedded/nanobsd
-
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.

If yes, how would I access them?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.
