Injecting a sequential job

[Svein Seldal]

Hi

I'm working on an embedded system using armel Ubuntu Natty, and I want 
to inject a sequential task (script) rather early in the boot (after 
filesystems/mountall, prior to network). The job needs to finish before 
the next tasks can run.

Specifically, I'd like to start my job with start on filesystem, but can 
I postpone the other tasks (particularely dbus and udev) until my job is 
done? (That without modifying dbus.conf and udev.conf as this is not 
permitted according to Debian Policy Manual)

If I set my task job to "start on stopping mountall" would that delay 
the emits (filesystem, mounting, etc.) until my task is done?


Best regards,
