Thanks, Quinn, for taking the time to forward this to your contact on the HFS team, and for their comprehensive reply. Together with an excellent technical article in the Macintosh Developer's Journal, I think I've got all the information I was looking for.
Except for one last nagging question. Looking at the boot logs, I'm pretty sure I know the answer but I'm still looking for a definitive statement.
When you boot OS X in single user mode, the root filesystem is mounted
read-only. When a journalled HFS volume is mounted read-only, is the
journal still replayed? From my casual testing, it appears that it is
-- despite the fact that this sort of goes against the concept of
"read-only".
If anyone has any information on the behavior of an HFS journalled filesystem when mounted read-only, I'm dying to find out.
