Yes they do.

In case of such transitions, upon executing the script, the context is
already initrc_t (in the system_r role). The SELinux code that OpenRC calls
checks the current context, sees that it is not run_init_t and gracefully
returns (no further actions taken) and the "normal" flow continues.

Indeed. I wouldn't mind splitting the init code into their respective
domains, although that will be a "hell of a job", while there are still
important shared aspects to it.

Indeed.
