Note you use slave and private somewhat interchangeably above. Which you want to use will depend on the behavior you want to see if the uesr tries to umount something under /home. If there might be devices or remotes which need to be freed, then you'll wan to use slave so that the chroot can't pin the source. If you actually want the mount to stick around in the chroot then you'll want to use private.
