I can't argue with you because I'm also using dhcpcd, but for
a totally different reason. I have to restart some IPSec VPN's when
ever things change and the .info file that dhcpcd generates is ideal
for sourcing into the scripts that reconfigure freeswan. I guess pump
could be beat into submission with some scripting, but why bother. So
I am also on dhcpcd.
Now... If I could just stop EITHER of them from replacing my
default route (my default route goes out my dedicated ISDN lines) I
would be a happy camper.
BTW... I have already experienced one occasion where my lease
expired and a new address was negotiated. Dhcpcd was running at the
time and handled it fine. Unfortunately, IPSec did not, which is why
I'm having to do all this scripting. I also have to do dynamic updates
to my DNS when that leased address changes, adding yet another complication.

But don't forget /sbin/ifdown! I found that out the hard way
when I had to restart the interface for other reasons and discovered that
pump was being called in /sbin/ifdown to shut down. DON'T just replace
pump with "dhcpcd -k" though! That will "release" your lease and return
the address back to the dhcp server. Not likely to be what you want to
do. You want to get the dhcpcd pid and send a SIGTERM to that pid.

Well then tell us, what version have you tested. I still can't
tell what version you are talking about and the versions are radically
different enough that any statement made about "all versions of pump"
are highly likely to be irrelevant.
One of the other reasons I'm down on pump is that it has changed
SOOOO much over the last few revs that I just don't trust it to be stable.
I also have a new reason not to trust it, now. RedHat 7.0 seems
to have a problem that may be related to THAT version of pump. My son
installed RedHat 7.0 on his system and set it to aquire an address from
dhcp (which happens to be running on another Linux system here).
Everything seems to be fine for a day or so but then he looses the
interface address (ifconfig shows no IP address). If he does an ifdown
and then and ifup, everything is restored to normal with the address
he had previously aquired from dhcp. It DOES closely correspond to the
lease time, so pump may have aquired some new BUGS on the road to 7.0.
Scott and I are now in diagnostic mode trying to determine if
pump is busted even worse on 7.0 than it ever was before. We're waiting
for the interface to go dain bramaged again to see if pump is still
running on his system and then we are switching him over the dhcpcd.
Right now, pump is the prime candidate for the cause of this problem
This is NOT with a broadband cable system to his system and he is NOT
changing addresses. I control THAT dhcp server and it's a stock ISC
dhcpd running on another RedHat system over ethernet.
IMNSHO: I agree with you on several levels that pump should
be dumped. It has not supported all the features of dhcpcd, it has been
subject to radical changes in features, its support of various broadband
cable networks is questionable at best, and its stability is highly
questionable. It has been and continues to be a questionable effort
at reinventing a wheel that is pretty well covered by dhcpcd and/or
dhcpclient with no real advantages.
