Sorry.
You seem to be running the util-linux version of switch_root, not the Busybox one. In any case, give the absolute path in 'newroot', that is '/newroot', relative path won't work. See the source for why. Also, you should do # exec switch_root /newroot /sbin/init because you need to run the new /sbin/init as PID 1. This assumes that your shell is actually PID 1. If not, this won't work. baruch > ________________________________________ > From: Laurent Bercot [[email protected]] > Sent: Monday, October 03, 2011 8:18 PM > To: [email protected] > Cc: Dutta, Kanishka > Subject: Re: can't switch_root > > > Yes, initially I am booting up with minimal initramfs. > > Well in that case you cannot use pivot_root, and have to use switch_root > indeed. > (You could also clean up your filesystem by hand and then mount --move, > but that offers no real benefit over using switch_root, which does exactly > that for you.) > > Could you send the output of a strace of your switch_root command ? -- ~. .~ Tk Open Systems =}------------------------------------------------ooO--U--Ooo------------{= - [email protected] - tel: +972.2.679.5364, http://www.tkos.co.il - _______________________________________________ busybox mailing list [email protected] http://lists.busybox.net/mailman/listinfo/busybox
