It's not. This is all completely configurable. You can have it apt-get update/upgrade/dist-upgrade at the start of every build. update is enabled by default (needed to ensure build-deps can be installed and sources can be fetched), but dist-upgrade is not (historically out of concern things might break). Now we are using snapshotted chroots for all or most buildds, the risk is far less and if the worst does happen you can just restore an older snapshot or re-debootstrap, which takes all of 5 minutes. You could, for example, have the source chroot dist-upgraded using "sbuild-update -ud" via cron on a daily basis, and every build also do a dist-upgrade to ensure the build chroot is always completely up to date. Before we had snapshotted build chroots, and had to manually uninstall all build-deps, the chance of a dist-upgrade breaking a dirty chroot was non-negligable. But if the source chroot is a minimal debootstrap which is always kept clean (i.e. the buildd admin should never customise it in any way), it should always be safe to upgrade bar any major SNAFU on the part of a base package maintainer which breaks the base system. On the sbuild side, we could revisit the default for end users and buildds and enable dist-upgrade by default for one or both of these if there's consensus that this is desirable and safe to do.
