In this case, if find had an error it would print the result to /dev/null, return a non-zero exit, and then have that fixed to 0 by the test command.

What I'm saying is that this doesn't tell anybody else who looks at your question how they might solve the problem for themselves.

@EvanLi If you're using a "flat" network and providing your own DHCP service, then yes -- an appropriate boot image supporting PXE can be used and you'll have PXE booting.

@EvanLi You'd have to modify the source code of the product to provide an interface for PXE options to be entered and appropriate mechanism of passing those options to the underlying dnsmasq process.

@MichaelHampton The surrounding framework of the cloud needs to support passing those options, though. I'm working on implementing that in a related product that uses KVM, actually.

Doesn't the PXE process need appropriate DHCP options? Unless OpenStack's system allows setting those parameters, I'm not sure this will help.
