Anaconda buildinstall: "latest: command not found"

[Kenneth Porter]

So where do I find the command "latest"? I'm guessing this figures out the 
latest release of the installed kernel, but I want to confirm. From my 
invocation of buildinstall:

Running buildinstall...
/tmp/FCBASE/fc4/i386/buildinstall.tree.21763 /tmp/FCBASE
/tmp/FCBASE
Going to run buildinstall again
Building images...
Assembling package list...
/tmp/FCBASE/fc4/i386/buildinstall.tree.21763/upd-instroot: line 50: latest: 
command not found

I'm also posting here:

Has anyone outside Red Hat successfully built a FC4 installation CD with a 
custom kernel? All I want to do is add support for an older megaraid 
controller by adding its PCI ID's to the driver's internal table. (It's an 
"i4 100" IDE RAID controller.) I've got the custom kernel RPM built and now 
need to integrate it into the installer image. (I tried loading just the 
new module from the stock "linux rescue" boot but the new megaraid_mbox.ko 
refuses to insmod and I get no error message.) More on that issue here:
