Ok. Reading the pivot_root man page (<a href="http://linux.die.net/man/8/pivot_root">http://linux.die.net/man/8/pivot_root</a>) to change the root fs mount /dev/hda1 /new-root cd /new-root pivot_root . old-root exec chroot . sh <dev/console >dev/console 2>&1 So I changed exec chroot . sh -c 'exec /sbin/init' <dev/console >dev/console 2>&1 to exec chroot . sh <dev/console >dev/console 2>&1 I do not see any complains, but the /proc dir is empty now. If I try to change run level though I get telinit 5 telinit: Unable to send message: Connection refused Thank you, Luca On Thu, Dec 17, 2009 at 9:06 AM, Konstantin Svist<<a href="mailto:fry.kun@gmail.com">fry.kun@gmail.com</a>> wrote: <div class="gmail_quote"><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"><div class="im">On 12/17/2009 08:41 AM, Luca wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> #!/bin/bash cd /tmp mkdir newrootfs mount rootfs.img newrootfs cd newrootfs mkdir oldrootfs pivot_root . oldrootfs exec chroot . sh -c 'exec /sbin/init' <dev/console >dev/console 2>&1 I can see the new root is rootfs, but still there is something not working.
