Hi,

i am using linux for couple of years. suddenly i a question arises in my mind. Before loading kernel during booting linux box initrd image loads necessary real mount point, file system, modules etc. but how initrd loads them ?? is there predefined modules list stored in initrd image or something else....what is the background procedure of it..????

regards,
adnan

An initrd is compiled with cpio [options] |gzip [options]

Reading involves gunzip [stuff] |cpio [stuff]
