I would like to know how you could create a root filesystem on a rom image but have it transparently linked to a users home folder.
I wish to create a symbolic link to usr/bin within the users home directory for installation and uninstallation purposes, but also like how both osx and windows have their programs directory in the home directory, but I don't know how to create a transparent user filesystem.
I know about xdg, for the desktop, documents directories, etc. But I want to know how to create a hidden programs and system directory, while keeping the rootfs hidden. Is that possible?
