Nope, that wasn't my question. Rather, I'd like to know why the OP wants to use switch_root in his initrd instead of pivot_root, as the latter is easier to use and already included in ubase. And it doesn't depend on the filesystem type of the initrd. Also, the shell script I posted was a mockup. It probably doesn't work like that as drop-in, because for one it calls chroot and then does stuff after that. I just didn't want to write all that in C as that would have been way longer. I didn't deem it necessary for the purposes of demonstration. Ciao, Markus
