Accessing the chroot is not really possible.

I would first check some of the common problems, which includes use of
absolute file names such as /bin/sh or /usr/bin/env, use of reverse DNS
lookups (as discussed here recently), or use DNS lookups or network
access in general.

Commit 6dc9931 added details in the manual about what=E2=80=99s in the chro=
ot.
If you need more details, then I suggest looking at
nix/libstore/build.cc::initChild, which sets up the build environment.

HTH!
