Hi, Is there a way I can permit a user confined by selinux to run rpm but the scriptlets to be executed in user's domain type instead of rpm_script_t ?

I have a use case where I need to permit some users to install rpms but in same time I need to confine them so would not interfere with files that define network interfaces/kernel and so on.

I think you would need to define a domain transition from the user's domain type (let's say user_t) to a new domain (let's say user_rpm_t) upon executing rpm_exec_t so that rpm will run in that domain, and then define a domain transition back from user_rpm_t to user_t upon executing shell_exec_t so that rpm scriptlets will run in user_t. Or you could define a user_rpm_script_t domain for that purpose. If you define a domain transition, it will use that instead of using rpm_script_t. But you not only need rpm scriptlets to run in a different domain; you also need rpm itself to run in a different domain if you want to prevent the user from overwriting arbitrary files.
