I'm not saying that it's not a bug. Sorry if this was unclear. Just in case you missed it, I've forwarded this upstream: https://github.com/systemd/systemd/issues/7413 -- Why is it that all of the instruments seeking intelligent life in the universe are pointed away from Earth? signature.asc Description: OpenPGP digital signature

Thank you for your answer. >I don't see a -t parameter there. It looks like -t is a legacy command >line option which systemctl parses but ignores: Ok. However: * systemctl does not correctly parse (and ignore) the -t option, because this option is followed by a number that should be skipped as well. Either -t is an unknown option and shutdown should print an error message, or it is kept for compatibility reason and ignored and in this case it should be correctly parsed. * I was misled by the french manpage of shutdown that still documents the "-t" option. This localized manpage should be updated. Anyway, from my point of view it's a regression (on Jessie at least): my "shutdown -h -t 5 now" command was working (even if "-t 5" was ignored), and now it's not (i.e. the shutdown does not occur at the correct hour).

It looks like -t is a legacy command line option which systemctl parses but ignores: https://github.com/systemd/systemd/blob/master/src/systemctl/systemctl.c#L8126 -- Why is it that all of the instruments seeking intelligent life in the universe are pointed away from Earth? signature.asc Description: OpenPGP digital signature

I made a diff between systemd-sysv 215-17+deb8u5 (bug not present) and 215-17+deb8u7 (bug present), and there are 2 new patches (introduced in version 215-17+deb8u6) that may be related to this bug: * systemctl-fix-argument-handling-when-invoked-as-shutdown.patch * systemctl-when-reading-legacy-t-argument-for-shutdown-don.patch

Hi Michael, I can reproduce this bug on Strech as well (systemd-sysv 232-25+deb9u1). I think you should however also fix this bug on Jessie, because it is a recent regression (was not present on Jessie 8.6). Based on the package's recent changelog, it may be a regression of "systemctl: Fix argument handling when invoked as shutdown. (Closes: #776997)" introduced on 215-17+deb8u6 (it's just a guess, but it is the only recent fix on shutdown's argument handling). Regards Thomas

Package: systemd-sysv Version: 215-17+deb8u7 Severity: normal Dear Maintainer, *** Reporter, please consider answering these questions, where appropriate *** * What led up to the situation? Try to reboot the computer with: # shutdown -h -t 5 now * What was the outcome of this action? A shutdown is planned in 5mn, and "now" seems to be interpreted as the message to send to users. * What outcome did you expect instead? Shutdown should start immediatly, with a 5s delay before sending the kill signal. This problem was not present in Debian 8.6. I detected this problem in Debian 8.9 (but it may have appeared somewhere between 8.6 and 8.9). -- System Information: Debian Release: 8.9 APT prefers oldstable-updates APT policy: (500, 'oldstable-updates'), (500, 'oldstable') Architecture: amd64 (x86_64) Kernel: Linux 3.16.0-4-amd64 (SMP w/4 CPU cores) Locale: LANG=fr_FR.utf8, LC_CTYPE=fr_FR.utf8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages systemd-sysv depends on: ii systemd 215-17+deb8u7 systemd-sysv recommends no packages. systemd-sysv suggests no packages.
