Also, sometimes you have to release the old lease (on the
previously-active device, of course), or wait for it to expire.
Usually that would let me grab a new lease on a different device
without power-cycling the modem, and would occasionally be necessary
even after a modem reset.
This used to be accomplished with 'dhclient -r', but I'm not sure how
to do that with dhcpleased, even after reading the man pages...
ENOTIMPLEMENTED or am I overlooking something?
I also found dhcpleasectl's behavior of forcibly renewing a lease by
default, but needing a flag to just show the lease info, rather
backwards -- and was quite surprised that it didn't require root to
renew. I may be in the minority though.
