[SOLVED] Busybox rpm scriplets

Issue

I am packaging with rpm for embedded device with busybox instead normal GNU system. When I install with busybox, it install module, but do not even try to run scriplets. On regular system, It runs them and fails(ofc, another version of kernel).

Question: Where am I wrong, and how to work around it? Here is my spec-file:

# The kernel version you are building for  
%define kernel 3.4.0-rc6-01292-g9b8149d  

# The name of the module you are supplying  
%define modname ktgrabber  
# The path to the module, after it is installed  
%define modpath /lib/modules/%{kernel}/kernel/net/ipv4  

# Which revision are we on  
%define pkgrelease 1.SL  

# Is this a new module, or are we replacing an existing module  
# 1 - new module  
# 0 - replacing an existing module  
%define newmodule 1  

# Optional - what Architecture we are building for  
#%define thisarch ia32e

Solution

Check out this link : http://lists.busybox.net/pipermail/busybox/2006-November/059507.html scriptlets aren't run by busybox's rpm command.

Looking at the source at http://git.busybox.net/busybox/tree/archival/rpm.c#n149 that appears to be true.
