To calculate - * the size of the message, use "offsetof(struct sd_shutdown_command, - * wall_message) + strlen(command.wall_message)". - * - * To cancel a shutdown, do the same, but send a fully zeroed-out - * structure. - * - * To be notified about scheduled shutdowns, create an inotify watch - * on /run/shutdown/. Whenever a file called "scheduled" appears, a - * shutdown is scheduled. If it is removed, it is canceled. If it is - * replaced, the scheduled shutdown has been changed. The file contains - * a simple, environment-like block that contains information about - * the scheduled shutdown: - * - * USEC= - * encodes the time for the shutdown in usecs since the epoch UTC, - * formatted as a numeric string. - * - * WARN_WALL= - * is 1 if a wall message shall be sent - * - * DRY_RUN= - * is 1 if a dry-run shutdown is scheduled - * - * MODE= - * is the shutdown mode, one of "poweroff", "reboot", "halt", "kexec" - * - * WALL_MESSAGE= - * is the wall message to use, with all special characters escaped in C-style. - * - * Note that some fields might be missing if they do not apply. - * - * Note that the file is first written to a temporary file and then - * renamed, in order to provide atomic properties for readers: if the - * file exists under the name "scheduled", it is guaranteed to be fully - * written. A reader should ignore all files in that directory by any - * other name. - * - * Scheduled shutdowns are only accepted from privileged processes, - * but anyone may watch the directory and the file in it. - */ - -#ifdef __cplusplus -} -#endif - -#endif diff --git a/units/.gitignore b/units/.gitignore index ad469c1041..d81d0c587a 100644 --- a/units/.gitignore +++ b/units/.gitignore @@ -59,7 +59,6 @@ /systemd-resolved.service.m4 /systemd-hibernate-resume@.service /systemd-rfkill@.service -/systemd-shutdownd.service /systemd-suspend.service /systemd-sysctl.service /systemd-sysusers.service diff --git a/units/systemd-shutdownd.service.in b/units/systemd-shutdownd.service.in deleted file mode 100644 index d951742500..0000000000 --- a/units/systemd-shutdownd.service.in +++ /dev/null @@ -1,15 +0,0 @@ -# This file is part of systemd. -# -# systemd is free software; you can redistribute it and/or modify it -# under the terms of the GNU Lesser General Public License as published by -# the Free Software Foundation; either version 2.1 of the License, or -# (at your option) any later version. - -[Unit] -Description=Delayed Shutdown Service -Documentation=man:systemd-shutdownd.service(8) -DefaultDependencies=no - -[Service] -ExecStart=@rootlibexecdir@/systemd-shutdownd -NotifyAccess=all diff --git a/units/systemd-shutdownd.socket b/units/systemd-shutdownd.socket deleted file mode 100644 index 9421ce8ada..0000000000 --- a/units/systemd-shutdownd.socket +++ /dev/null @@ -1,18 +0,0 @@ -# This file is part of systemd. -# -# systemd is free software; you can redistribute it and/or modify it -# under the terms of the GNU Lesser General Public License as published by -# the Free Software Foundation; either version 2.1 of the License, or -# (at your option) any later version. - -[Unit] -Description=Delayed Shutdown Socket -Documentation=man:systemd-shutdownd.service(8) -DefaultDependencies=no -Before=sockets.target - -[Socket] -ListenDatagram=/run/systemd/shutdownd -SocketMode=0600 -PassCredentials=yes -PassSecurity=yes |
