[sorry if duplicate, keyboard error... tab key or something with the webmail]

Having experienced similar errors during single user mode installword, I was
wondering if a FLAG or --switch could be added to "make installworld" so that
all the $cc >> actual binary [precheck] and all the expected directories that are destinations
exist and are not files [precheck] , and optionally even a trial-run-install-to-elsewhere "check
for such errors" pre-install runthough, like "-n" in other cli [binaries].

OR a section in UPDATING with a proven [iow, tested on
several and many ... mfsBSD... DESTDIR... cdr... etc ] procedure to accomplish the same...

The lack of which is precluding upgrading very often now, as opposed to other years, 
since CURRENT...
