Relying on start priority levels seems fragile, esp. with systemd which "provides

Matahari could be changed to read /etc/vm_machine_id first. If that

This creates some difficulty in running the audrey script at a specific
runlevel (it requires some changes to oz to insert init scripts).
To express such dependency you could use LSB initscript header Required-Start: in matahari
initscript (which one, matahari-host I guess?)
but such dependency in Matahari doesn't seem right.
In systemd unit file you could specify Before and After, but that's only for Fedora
Another option is for the current rc.local script that audrey
to run the Matahari service starting giblits as its first action.
That actually might be the most reliable and portable way.
