Hi Markus,

I´m not sure about your requirement, maybe you are looking for the rc.once mechanism, too. rc.once is running once per target on the very first run.

The package mechanism works every time you upgrade/install a package with opkg/ipkg to the already running target. Let´s say you have a package called mypackage. This package is represented by two files in the rules directory of your project $PTXDIST_WORKSPACE/rules/mypackage.in and $PTXDIST_WORKSPACE/rulse/mypackage.make. You can create a postinst script by creating a "executable" file named $PTXDIST_WORKSPACE/rules/mypackage.postinst.

A short example content of this file could be:

#!/bin/sh
echo "running postinst script of mypackage"
/sbin/create_a_cool_user.sh
/sbin/call_some_fancy_binaries.sh
exit 0

It is important, that your script always succeed (return 0). As Michael mentioned this script is called when your rootfs is assembled. This script is called by opkg when upgrading or installing this package via opkg/ipkg to your already running target, too.

Hope this helps.

Regards
Gavin

Hello Michael,

I'm not quite sure if I got it right. I need to create an user and start some executables on the already running target for example. Is that possible with your solution?

Just create "rules/<package>.postinst". There are some examples in PTXdist.
Note: PTXdist will call the script when creating a rootfs. In this case
$DESTDIR is set to the path where the rootfs is assembled.
