Sorry.  You could have also overridden the kernel options in koan itself:

    * koan ... --kopts='ip=10.xxx.xxx.19 netmask=255.255.254.0
      gateway=10.xxx.xxx.253 dns=10.xxx.xxx.117'

Basically koan doesn't make use of the cobbler's own --ip, --gateway, 
--subnet variables when interfacing with grubby to create the grub 
config file; rather it /only/ makes use of --kopts.  This is rather 
nonintuitive, and it's difficult for me to think of a situation where 
one is attempting to reprovision (via koan --replace-self) a system, yet 
not want import those cobbler dictionary values (ip, subnet, etc.) into 
grub kernel arguments.

Then, there is the problem of precedence: do --ip, --subnet, etc. 
override --kopts='ip=... netmask=...' if both are declared?  Or vice 
versa?  This is a policy decision which Michael shouldn't have to worry 
about enforcing.  Rather, it may be more relevant to update the cobbler 
wiki under 'koan replace-self procedure'.
