Nope, 'exit 1' is the currently correct way to defer to first boot. On 
the other hand, it's also a correct way to indicate that the script has 
failed, and rpm is right in reporting it as such. This is a design 
defect in Yocto, and I plan to fix it, so that instead you would simply 
write your fragment as follows:


pkg_postinst_ontarget_PACKAGENAME() {
       # Actions to carry out on the device go here
       ....
}
