Host OS - archlinux
Destination - opensuse on /dev/sda2
I always mount /proc and /sys with these options and so far it worked perfectly.
[root@archlinux ovi]# mount /dev/sda2 /media/suse/
[root@archlinux ovi]# mount -o bind /dev /media/suse/dev/
[root@archlinux ovi]# mount -o bind /dev/pts /media/suse/dev/pts
[root@archlinux ovi]# mount -o bind /proc /media/suse/proc/
[root@archlinux ovi]# mount -o bind /sys /media/suse/sys/
[root@archlinux ovi]# cp /etc/resolv.conf /media/suse/etc/resolv.conf
[root@archlinux ovi]# chroot /media/suse
