Hmm. Interesting reading, but it seems like you haven't really gotten into the interesting parts. Sparse-root zones are one of the key pain points. Eliminating them makes life easier... but then again, if we could eliminate them, life would be easier for SVR4 packaging too. As a person developing an application for deployment onto a Zones system, sparse-root zones are probably my biggest Zones headache by far. Zones aren't completely independent of the global zone. Better not install a libc that's newer than the kernel that's running. One of the key advantages of zones over multiple systems or over VMs is that in many cases you can ignore them and just manage the global zone, and the local zones will just take care of themselves. The more that they differ from one another, the less that works and the more complex the management processes are. Eventually you end up with something that looks like a multi-system management infrastructure. Those work, but they tend to be pretty big and complicated, considerably more complex than having "pkgadd" update all of the zones at once. Being willing to change the basic assumptions is a good thing, and usually one of the only ways to get serious improvements. Just make it clear how much baby is in the bathwater. _______________________________________________ pkg-discuss mailing list [email protected] http://mail.opensolaris.org/mailman/listinfo/pkg-discuss
