I have always maintained that init system, is only critical choices, because the cloud/cluster technologies are not yet mature. What you get from these init system, can easily be established with a few files at boot time (PXE and many others methods), that is what CoreOS is doing, just in an updated fashion. > In any case, the whole point of both ChromeOS and CoreOS is that > they're hosts for running applications completely outside of the usual > unix-y approach of sticking stuff in /usr.

Yes, your are correct, that is what the "cloud" vendors are striving for. I see a much deeper future, that leverages their ideas to invigorate Gentoo. In the good old days, it was very common for folks to build up minimized gentoo sytems, by starting of with "-*" in the USE settings of make.conf. Sure now that sort of thing is frowned upon by the devs, but it was and is a very valid method to minimize the size and complexity of a system. I still have running gentoo sytems with just a few flags set and with "-*" in the USE settings. I do not sync them, but update them selectively in a manual process. This yeilds a linux system, usually for a special purpose, that is so minimized it's very close to a stipped/optimized embedded system. WE seem to have lost the "embedded" focus here at gentoo. Gentoo-embedded, as a discussion/sharing group seems to be dead; but I think it is because most are slobberingly working on 64 bit arm offerings. Minimized sytems can be delivered via something like CoreOS and then the other codes (binaries whatever) can be added dynamically to yield a very focused target system, a replacement system, or a parallel system to handle a dynamic resource loading problem, jus to name a few reason for the CoreOS approach to building up a cluster. I do not see the "/usr" types of systems (like a current gentoo workstation or server) going away any time soon. What I hope WE can pull off at Gentoo is integration of the best of the CoreOS ideas into "Gentoo proper". I was just very surprised to stumble across CoreOS; as it is what my hopes (vision?) of Gentoo are to be, beside continuing the traditional linux progression (/var/usr/local/home/etc..... )type of unix derivative OS. I do believe that this traditional linux (what's left of unix) belongs to the masses and "force feeding" of systemd was a very, very poorly made decision. I do see the "Cloud vendors" eating away at the Microsoft and Apple user base and large companies with masses of "clerical" employees. So, to sum this up, in my view, is to say that CoreOS (ideas) offers us a pathway to be able to build (via dynamic downloads) any system we want from a minimized linux state machine on a 16 bit core, to a "-*" minimized gentoo system or a full gentoo linux workstataion or server. Substitute "cluster controlled by user" for "cloud" and I really like the CoreOS vision. I think they have stolen the "Gentoo Grand Unification Theory" from us, because we are "napping" here at Gentoo. Just so folk know, a minimize system is far easier to keep secure, and replace dynamically for whatever the failure reason is. I guess that CoreOS is just building up clusters from derivatives ot TFTPboot...... That is what's old (farts) is new again, as it appears we are returning full circle. YiPeeeeeeeeeeeee! James
