Just thought I'd share with the group something I took a while to
figure out....  :)

I prefear my machines to boot totally off local disk (under normal operation)
without getting their kernels over the network (hey, I'm weird like that :).

However I would also like them to be configured to boot from the network
by default so that I don't have to go frikkin' around with BIOSs on loads
of machines whenever I get the urge to re-install them.

You can use the following PXE config in /tftp/pxelinux.cfg/default

    DEFAULT local-boot
    LABEL local-boot
    LOCALBOOT 0

Which, assuming theres no other config matching the ip of the machine, 
will tell it to boot, surprisingly, from the local disk.

You can then create a specific config for the machine(s) whenever you
want to re-install. fai-chboot(8) does this if you are using fai... 

*shrug*

Probably something terribly obvious which everyone knows... but I
was thrilled when I found out it could be done :)
