I guess it depends on the vendor. They may not be able to provide ranges, they may just have to provide lists. The assumption would be that they know what MAC a particular system has when it ships. A database of millions of MACs instead of ranges isn't inconceivable: a system name table, plus 6 bytes per MAC, plus a generous 4 bytes offset into the system name table per MAC, for 10,000,000 systems, is <100MB uncompressed. > > What happens when a machine tries to boot and gets fed an incorrect > image?

Even if they did, I don't think we can rely on this behaviour. Some hardware may require, say, an additional kernel parameter to activate some desirable feature, but can run without too. > > Even if MAAS no longer controls the DHCP server, does it still get to > listen to these broadcast requests?

I think it's worth considering. -- Mailing list: https://launchpad.net/~maas-devel Post to : [email protected] Unsubscribe : https://launchpad.net/~maas-devel More help : https://help.launchpad.net/ListHelp
