Is there some special way of chrooting into this rootfs?

If I just bindmount dev and proc into the rootfs, then chroot into it and try to apt-get install some packages, I get:
/bin/sh: line 1: /usr/sbin/dpkg-preconfigure: No such file or directory
Can not write log, openpty() failed (/dev/pts not mounted?)
Segmentation fault

I'm trying to search on chrooting onboard N900, but not much I found.
