chroot gives /bin/bash not found error message

[increa]

I'm going through the X86 Quick Install document. Things work well until I tried to chroot to the new /mnt/gentoo root. At that point /bin/bash is id'ed as unavailable, and so is /bin/sh. I even tried explicity specifying the cdrom location. Same result. Both shell executables run fine when used alone on the command line. Why is the chroot command not finding them? Console dump:

livecd / # uname -a
Linux livecd 2.6.17-gentoo-r7 #1 SMP Mon Sep 18 01:26:27 UTC 2006 i686 AMD Athlon(tm) Processor GNU/Linux
livecd / # chroot /mnt/gentoo /bin/bash
chroot: cannot run command `/bin/bash': No such file or directory
livecd / # ls -l /bin
lrwxrwxrwx 1 root root 15 Oct 9 07:41 /bin -> /mnt/livecd/bin
livecd / # chroot /mnt/gentoo /mnt/livecd/bin/bash
chroot: cannot run command `/mnt/livecd/bin/bash': No such file or directory
livecd / # ls /mnt/livecd/bin/ba*
/mnt/livecd/bin/basename /mnt/livecd/bin/bash /mnt/livecd/bin/bashlogin

A similar posting titled, "Cannot CHROOT into native install" covers this same basic issue, but that poster had the problem solved by properly mounting partitions. I think mine are:

livecd ~ # mount
tmpfs on / type tmpfs (rw)
/dev/hdc on /mnt/cdrom type iso9660 (ro)
/dev/loop0 on /mnt/livecd type squashfs (ro)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
udev on /dev type tmpfs (rw,nosuid)
devpts on /dev/pts type devpts (rw)
cachedir on /mnt/livecd/lib/splash/cache type tmpfs (rw)
tmpfs on /mnt/livecd/lib/firmware type tmpfs (rw)
tmpfs on /mnt/livecd/usr/portage type tmpfs (rw)
usbfs on /proc/bus/usb type usbfs (rw,devmode=0664,devgid=85)
/dev/hda2 on /mnt/gentoo type ext3 (rw)
/dev/hda4 on /mnt/gentoo/home type ext3 (rw)
proc on /mnt/gentoo/proc type proc (rw)
livecd ~ #

Any help surely appreciated. This seems like such a trivial issue compared to everything else I see posted, but I'm stuck!

I could be wrong however the target /bin/bash should be in /mnt/gentoo/bin/bash not on the cdrom. Check to make sure the /bin/bash is in your /mnt/gentoo other wise you make have to re-untar the stagefile to make sure its gets up in the right place.

My /mnt/gentoo/bin directory is empty. The stagefile was downloaded into the /mnt/gentoo/usr directory and untarred there, per the X86 Quick Install document, giving a /mnt/gentoo/usr/portage directory with lots of files in it.

Can you clarify, "otherwise you may have to re-untar the stagefile to make sure it gets set up in the right place" ? Where is the right place?

Just to try, I manually copied the bash executable over to /mnt/gentoo/bin. The chroot command gives the same error. It would be good to know, given the "chroot new-root start-command" syntax, does the start-command execute in the new context of the new-root? If so, I have to agree there should be a bash file under the /mnt/gentoo tree. How would it have gotten there if the Install Guide says untar it under the /mnt/gentoo/usr directory?

[rokstar83]

I think you skipped a step.

tar -xjpvf x86-stage3.tar.bz2 -C /mnt/gentoo

To get the base files into your future root directory. Then you untar you portage tree snap shot.
I would recommend that you use the full gentoo handbook and not the quick install. My impression is that the quick install is for folks who have done the installation a lot of times and just need the steps to remind them what to do and the right order.
