My inclination is to say that for now the "standard" FreeBSD images should include all the bits which 'make installkernel installworld' provides. (I have been considering shipping no-debug-files EC2 AMIs as an additional option, though, since people pay per GB for storage there.) When we move to pkgbase it will become dramatically easier for users to install debug files if/when needed, and at that point I think it would make sense to ship without them by default. -- Colin Percival FreeBSD Release Engineering Lead & EC2 platform maintainer Founder, Tarsnap | www.tarsnap.com | Online backups for the truly paranoid
