The quick commands are just aliases for the `boot` command with
various pre-cooked kernel/initrds/cmdline combinations. Currently
supported are Debian, Ubuntu, Fedora and Centos. There's also code
for Arch, but it's currently disabled as I'm failing to get the
HTTP rootfs to work.
The two binaries (Apache2 and GPL) both invoke the cli package to do
the work, the only difference between them is that the GPL binary passes
it embedded ipxe binaries.
