post-installation scripts vs. init scripts

post-installation scripts vs. init scripts

[Peter Gejgus]

Hello,

I've checked experimentally that post-installation scripts (executed during the first boot) run before init scripts. I've checked it by putting long sleep into the following script and I've also verified timestamps from init script and post-install script in the log:

pkg_postinst_PACKAGENAME() 
{
     #!/bin/sh -e
     if [ x"$D" = "x" ]; then
          # Actions to carry out on the device go here
          sleep 300
     else
          exit 1
     fi
 }

Can you confirm that post-install scripts run before init scripts and there is no overlap?

Regards,
Peter

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).
