I found out how to modify ptxdist to get the script substituted.
But, doing this will not be reflected in the scripts run by ptxdist as these are run from their original location.

Diff below would work for preinst script but not for postinst

I wonder why ptxdist does not use the host_compiled ipkg to perform the install step.

{Host_ipkg_path}/ipkg-cl -o ${PTXDIST_ROOT} install ${PTXDIST_PLATFORM}/package/mypackage_trunk_armel.ipk

I tried it and it works

I was wrong, the IPKG_OFFLINE_ROOT is set if in offline mode
