You can build chroot in just a separate folder using debootstrap. chroot is not fully fledged VM in meaning of hardware abstraction. It is just a way to make files (executables, libraries, settings) inside a folder "/opt/chroot-sid-amd64/" *believe* they are in "/". So if you change some settings inside chroot "/etc/" they will actually be changed in "/opt/chroot-sid-amd64/etc/". This is why chroot is convenient to try things, install tons of -dev and dependency packages without cluttering or breaking actual working system. I recommend to read manuals for "debootstrap" and also "schroot" can make creating multiple chroot-ed environments more straight forward, eliminating the need to setup some settings manually, such as bind mount system partitions like "/sys" into chroot.
