The -current system isn't updated yet, just running buildworld. 
There's no problem regenerating the core dump.

I've gotten as far as

root@www:~ # lldb --core ./fsck_ffs.core
(lldb) target create --core "./fsck_ffs.core"
Core file '/root/fsck_ffs.core' (aarch64) was loaded.
(lldb) 

Typing "gui" brings up a curses window, but I've no
idea what to do next. 

Some guidance will be needed to make further progress.
Is there a beginners's tutorial somewhere?

Apologies for the naive questions!
