We work at it, but it is difficult to cover everything.  It would be 
nice to have a section in the Handbook on devd.  If you would like to 
submit or work on something like that, I can help (I'm a doc committer).

There are several similar ways to deal with the device name.  For 
example:

   action "ifconfig `echo $device-name | sed -e 's/axge/ue/'` name olan inet 192.168.1.1/24";
   action "ifconfig ue${device-name##axge} name olan inet 192.168.1.1/24";

(Untested, and sorry about wrapping.)  Both examples use the shorter 
CIDR notation for the netmask, and set the name and IP address at the 
same time... which ought to work, but I did not test.
