That also is an interesting angle to it. sbuild didn't ask for systemd-sysv to be installed. It was installed due to Build-Depends of some package. A different package might depend on sysvinit-core where telinit writes to /run/initctl. Other telinit may do different things. Handling all of telinit internals in one pid1 does not seem reasonable to me, so the consequence of this would be that you shouldn't install telinit in a build chroot and we could file bugs about any package doing so. A particular consequence of this would be that you couldn't use libpam-systemd or dbus-user-session in transitive Build-Depends. We'd render a significant number of packages bd-uninstallable. On the other hand, you have exactly the same problems when switching your pid1 implementation (where we urgently advise rebooting to avoid these kind of problems). That said, a sysvinit-core telinit likely wouldn't break a container's tini/dumb-init nor break a systemd running as pid1. Helmut
