Comment 8 for bug 1879012

> Not sure if we want a feature to automatically scan/find grub.cfg on remote host by ip/mac/uuid/etc:

Currently MAAS only specifies the path to the bootloader, not the bootloader config. It expects the bootloader will automatically request the config from where the bootloader was downloaded from. Right now that is <server>/grub/grub.cfg. That file attempts to chainload <server>/grub/grub.cfg-${net_default_mac} and if that fails <server>/grub/grub.cfg-default-amd64. MAAS could also respond to <server>/grub/grub.cfg-$uuid as we have that information as well. Having grub do that automatically would remove a request and a level of chainloading.
