I took a look at the code, and it seems to come from a struct utsname as
defined sys/utsname.h (see man 3 uname as well). I think this struct is
defined at boot time from, amongst others, sysctl kern.hostname
A sysctl kern.hostname shows the machine name as well. Perhaps the
initialization does a conversion to lowercase?
