that each customer can run their own particular version of apache

I have no scripts for setting up a jail, don't ask me for them.
The IP number should be an alias on one of the interfaces.

. #include differences between the systems
. different callout handling between FreeBSD vs. Net/OpenBSD
. interface naming (Net/OpenBSD store the ASCII name including the
unit # in struct ifnet, FreeBSD only the name)
. use of random() in FreeBSD vs. time-based pseudo-randomization in

ioctl() routine at the end of if_delmulti() so that interfaces with
hardware multicast filtering can update their filters in a timely
manner.
If the interface doesn't support hardware multicast filtering, then
reception of multicast frames is done using 'promiscious mode' or
'capture all multicast frames' mode and software filtering in the
kernel. In this case, it doesn't matter if if_delmulti() ever does
an SCIODELMULTI on the interface or not: if MULTICAST support is
enabled, then we join the 'all hosts' group when the interface is
configured, and remain in it until the interface is brought down.
Without hardware filtering, joining one group means joining all
groups, so it makes no difference if we call the SIOCDELMULTI
routine.
If the interface does support hardware multicast filtering, then
by not reprogramming the hardware filter in if_delmulti(), we have
to wait until somebody calls if_setmulti(), during which time the
interface is receiving frames for multicast groups in which we are
no longer interested.

looutput is now static.
Other callers who want to use loopback to allow shortcutting

of whether one should be using the charateristics of the loopback interface

2.3.0 -> 2.3.1 changes, but I seem to recall that there are certain
"issues" with 2.3.1 (I'm not sure if it's just pppd or the whole lot, I
am not quite that far). The present pppd seems to work with it just fine
for the time being.
Among the changes are that zlib (aka LZ77 aka deflate aka gzip) compression
is implemented as well as the original compress(1) LZW style.
