Run an executable from InitRamfs

[ShibuThomas]

Hi ALL,

Is it possible to execute my application(eg.hello world program) from 
initramfs before switching to /sbin/init and after the execution of my 
application I want to  execute kernel Init?.

I generate my initramfs using dracut command.

My objective :from the initramfs itself I want to run an application 
which will  authenticate server in the network.

Regards,
ShibuThomas
