Ok. I will do that. The shell command which calls fakeroot is:

chroot $BUILD_ROOT su -c "cd $TOPDIR/BUILD && dpkg-buildpackage -us -uc
-rfakeroot" - $BUILD_USER < /dev/null && BUILD_SUCCEDED=true

All things done in the chrooted environment are done with a registered
qemu via the "binfmt" feature. But I could run this specific command
also by involving qemu directly. Any specific options I should call strace?
