So here you implicitely allow an update where the new os.type or
os.arch would be NULL, I assume that any definition in the system
should have those set, right ?

But here you cmpare to new->os.type, which could potentially be NULL
at this point. Shouldn't that be changed to old->os.type instead ?

indentation error, here we are closing the second "if"

Postponed with the indentation fix waiting for the 4th patch to be
resubmitted,
