[OE-core] post-installation scripts vs. init scripts

[ChenQi]

In OE, sysvinit scripts are executed one by one at start-up.
The post-install scripts are run at first boot via 
/etc/rcS/S99run-postinsts.

E.g.
We have:
1) /etc/rc3/S10bind
2) /etc/rcS/S03udev
3) /etc/rcS/S99run-postinsts

The execution sequence is 2) -> 3) -> 1).
