omshell

[Allie M Hopkins]

I was hoping someone had insightful answers for you because I struggled
with the same thing.  I resorted to your method of removing the host first
then adding it back with the new data.  You may want to try unset
statement, then update.  It seems I got something to work once upon a time,
but I can't remember the right sequence.  In the end it was easier to
delete-add.

I also simply search the lease file for any static addresses or ddns name
configuration.

Let me know if you come across something that works.

I guess I can work around this problem by removing the host entry and
adding a new one each time I want to edit one.  I'll have to store the
"statements" information somewhere else so I can repopulate it when I
create the new host entry.  Anyone have any other suggestions?
