Problems reloading ippools

This is sort of a repost of my question from 8/9 about ippools that
never got solved. I just now got around to looking into this again as
I have an immediate need to make it work.

The problem I am having is that while I can create ippool.conf, define
a simple table, and then load it and use it, I cannot change a pool,
or remove it using "ipfboot reload"

As an example if I define the following in ipf.conf

block return-rst in log quick proto tcp from pool/100 to any port = 25

and the following in ippool.conf

table role = ipf type = tree number = 100
{ 128.125.10.28/32; };

and then start ipf, there are no problems and things work.

ex.
[root@msg-mx4 ipf]# ipfstat -io
empty list for ipfilter(out)
block return-rst in log quick proto tcp from pool/100 to any port =
smtp

[root@msg-mx4 ipf]# ippool -l
table role = ipf type = tree number = 100
{ 128.125.10.28/32 };


However if I then try add an IP address to that pool such as
128.125.253.108 and then run "reload" the pool will not be
updated. The problems seems to come from the ippool -f <FILE> portions
of the reload command.

ex.

[root@msg-mx4 ipf]# /etc/init.d/ipfboot reload
0 objects flushed
load_pool:SIOCLOOKUPADDTABLE: File exists
Set 1 now inactive
filter sync'd
[root@msg-mx4 ipf]# ippool -l
table role = ipf type = tree number = 100
{ 128.125.10.28/32 };


Just doing a straight "ippool -F; ippool -f ippool.conf" yields the
same results.

[root@msg-mx4 ipf]# ippool -F
0 objects flushed
[root@msg-mx4 ipf]# ippool -f ippool.conf
load_pool:SIOCLOOKUPADDTABLE: File exists
[root@msg-mx4 ipf]#


So short of stoping and starting ipf (or rebooting) how are you
supposed to make changes to already loaded pools? I have tried on both
4.1.13 and 4.1.14 and have had the same results. It seems that once a
pool is loaded with a given number (in this case 100) it cannot be
changed without restarting ipf. I have noticed similiar behaviour if I
try and remove something from an existing pool.

Now the obligatory information that the FAQ recommends I include.
