Many questions about translators |

To design HPM (Hurd Package Manager) I need answers to the following
questions (at least to begin with):
1. Is it possible for an unprivileged user to override the
translator of a node with another translator (at least, in their
own view)? Basically, the question is if users' private HPM
instances would also be able to have / as target when the system
already has an HPM instance at that target (and thus the
installed software would be from both the system HPM instance
and the personal HPM instance, with the latter having
priority).
2. If yes on question 1, would this be insecure? For example, if
the user overrides a library used by a setuid program? (Then
again, if the program is running as e.g. root by setuid, it
wouldn't [at least shouldn't] see the files as the user does)
3. Is it possible to have one translator working on two nodes at
the same time (where the nodes have different meaning)? HPM
needs to build one target directory (node one), and then have
the interface directory where the user can control the manager
(node two).
4. Is it possible for a translator to provide different views of
the node for different users? For example, could each user have
their own list of packages they want installed and the HPM
translator would use ref-counting to install packages with
ref-count > 0, and/or perhaps even make different packages
appear installed for different users?
Any help greatly appreciated. Thanks.
