for this to work really well, i feel that there should be a way to
*insert* an address at the head of the list of addresses for a given
i've had "problems" where the "primary" ipv4 address was removed via
"-alias" and then a new address was added via "alias".
"alias" adds to the end of list, "-alias" removes arbitrarily from the
list, "delete" removes the head of the list, and the absence of the
alias keyword *sets* the head of the list (at the same time deleting
what was there). the "insert at the head of the list" bit is missing.
