The only thing to watch for there is for kernel-related things since
you're obviously running on the same kernel in the chroot.

This was the case with the descriptor passing bugs in Linux 2.0 kernels:
the Debian folk used chroots as you described. configure found that
descriptor passing worked fine (which it did, on the host's kernel)
even though it didn't on the target. They eventually added some code
to detect the buggy kernel versions at runtime.

Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
