Dev dir a chrootban? Most csinaltam egy probat:

ga-k8nf-9-3# mkdir /usr/local/chroot
ga-k8nf-9-3# mkdir /usr/local/chroot/bin
ga-k8nf-9-3# mkdir /usr/local/chroot/dev
ga-k8nf-9-3# mkdir /usr/local/chroot/etc
ga-k8nf-9-3# mkdir /usr/local/chroot/lib
ga-k8nf-9-3# mkdir /usr/local/chroot/libexec
ga-k8nf-9-3# cp /bin/sh /usr/local/
ga-k8nf-9-3# cp /bin/sh /usr/local/chroot/bin
ga-k8nf-9-3# cp -a /libexec/* /usr/local/chroot/libexec/
ga-k8nf-9-3# ldd /bin/sh
/bin/sh:
         libedit.so.7 => /lib/libedit.so.7 (0x800663000)
         libncurses.so.8 => /lib/libncurses.so.8 (0x80077e000)
         libc.so.7 => /lib/libc.so.7 (0x8008cb000)
ga-k8nf-9-3# cp -P /lib/libedit.so.7 /usr/local/chroot/lib/
ga-k8nf-9-3# cp -P /lib/libncurses.so.8  /usr/local/chroot/lib/
ga-k8nf-9-3# cp -P /lib/libc.so.7  /usr/local/chroot/lib/
ga-k8nf-9-3# cp -P /etc/termcap /usr/local/chroot/etc/
ga-k8nf-9-3# mount -t nullfs /dev /usr/local/chroot/dev/
ga-k8nf-9-3# chroot /usr/local/chroot /bin/sh
sh: can't access tty; job control turned off
# exit
ga-k8nf-9-3#

A jobcontroll shell problema, ne foglalkozz vele.
