-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I am quite puzzled by the structure of the resulting initrd image. If I have understood what is happening (and I must admit I am struggling) the following steps occur
1) the kernel calls linuxrc to run 2) linuxrc saves the contents of real-root-dev in its own initrd image 3) linuxrc then changes the real-root-dev to its own initrd image 4) linuxrc exits which causes the kernel to start /sbin/init in the initrd image 5) /sbin/init then loads modules runs scripts etc 6) /sbin/init recovers the saved original real-root-dev and pivot_roots to it. My question is, why go to great trouble to store and then change real-root-dev. Why can't all of the meat of the action just happen in linuxrc and then pivot_root to the original root?
