Problem with shutdown via ssh at FreeBSD 15.0

[Roger Marsh]

Hi

Using ssh logins from an OpenBSD box throughout:

I upgraded a test box from 14.2-p1 by 'freebsd-update fetch' and 'freebsd-update install' to 14.2-p7; then to 14.3-p5 by 'freebsd-update -r 14.3-RELEASE upgrade' and 'freebsd-update install' and 'reboot' and 'freebsd-update install' and 'reboot' and 'pkg upgrade' (pkg only) and 'pkg upgrade -q -y'; then to 15.0 by 'freebsd-update -r 15.0-RELEASE upgrade' and 'freebsd-update install' and 'reboot' and 'freebsd-update install' and 'reboot' and 'pkg-static upgrade -f -q -y' (interrupted by ^C when the 'running "pkg bootstrap -f" recommended' warning appeared) and 'pkg bootstrap -f' and 'pkg-static upgrade -f -q -y' and 'reboot' and 'freebsd-update install'.

Now 'shutdown -r now' after ssh login to test box does not give the 'Connection to xxx closed by remote host' and 'Connection to xxx closed' messages when test box has shutdown and is starting to reboot. Instead 'connection reset' and 'broken pipe' messages appear after the reboot has completed.

On a 14.3-p5 box the 'Connection ...' messages are given when the reboot has completed.

On a 14.3 box the 'Connection ...' messages are given when the shutdown has completed and before the reboot starts.

Is this the expected behaviour now?

The script below demonstrates the situation after the upgrade.
