If your root disk is writable you should automatically get a coredump in
the root dir. On SIGSEGV PID 1 will fork and create that coredump in the
child, so expect this coredump to belong to another PID than 1.

This suggests that your root dir was not writable hence the coredumo
could not be generated.
