That wasn't so much a technical question as a philosophical question -- we've inherited shutdown actions from how hardware in the 1980s worked, and since 'shutdown -h' doesn't have any clear meaning in a VM I don't know that anyone gave it much thought. Certainly I never did. I suspect that the difference between Linux and FreeBSD here lies in how our underlying Xen code handles shutdown events... to be completely frank, I don't even know which code handles it under Xen HVM. But it's probably a bad idea to change it now, since some people have learned the existing behaviour. -- Colin Percival Security Officer Emeritus, FreeBSD | The power to serve Founder, Tarsnap | www.tarsnap.com | Online backups for the truly paranoid _______________________________________________ [email protected] mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-cloud To unsubscribe, send any mail to "[email protected]"
