Yup. It seems like this was the intention here:
void
init_system_name (void)
{
if (!build_details)
{
/* Set system-name to nil so that the build is deterministic. */
Vsystem_name = Qnil;
return;
}
which is called from
static void
init_and_cache_system_name (void)
{
init_system_name ();
cached_system_name = Vsystem_name;
}
which is called from
DEFUN ("system-name", Fsystem_name, Ssystem_name, 0, 0, 0,
doc: /* Return the host name of the machine you are running on, as a string. */)
(void)
{
if (EQ (Vsystem_name, cached_system_name))
init_and_cache_system_name ();
return Vsystem_name;
Is --no-build-details just meant to be used during builds? If so, we
can just document that, I guess?
