The getpw{ent,uid,nam}() emulations in many DOS libraries (i.e., the
routines that set the pw_dir component of the passwd struct) do first
check for the existence of an environment variable HOME and return
its value. "\" is the fallback, often. Available user(s) are "root"
and sometimes "anonymous" or "nobody".

That might be used as a possible implementation strategy for
#'user-homedir-pathname.
