Over the years, I've grown to realize tat this is fundamentally
ill-defined: the domain name is the way to find the IP address of a host
you want to connect to.  The machine itself doesn't necessarily
have/need/use that info: some machines don't have any domain name, some
have several, the domain name(s) can change without the machine being
told, ...

IME, most cases where a piece of software wanted to know "the host's
domain name" it was either "wrong" (it didn't actually need to know) or
it could use any "unique enough" name.  So it might be worth digging
further into your problem to see if you can push it elsewhere: instead
of "set[ting] the system's domain name", make sure the software
doesn't need that domain name.
