Those two statements are incompatible. The UUID doesn't have to be stable 
between reboots, but it would be nice if it were.

Which bug?

But if we default to --ensure on boot, but to /etc, then we guarantee 
that:

1) testers of the distribution will see a "Read-only filesystem" error 
during boot and will fix it

2) people with standard /etc will have a stable UUID that is maintained 
across reboots

3) people who haven't rebooted yet will not have auto-start working after 
they first install D-Bus 0.94 (or 1.0).

It'll only be busted if the file doesn't exist already in /etc. So it's a 
once-per-machine thing, and that's assuming D-Bus wasn't installed with 
the system before your first real boot into it.

This will mostly affect our BSD friends who will build D-Bus from the 
ports tree, instead of having it installed with the base system.
