[CentOS] Delaying systemd reboot for a while
Hi, I'm in need of rebooting a server 1 minute after I give the command. I'm used to shutdown -r +1 which works as advertised. Now that shutdown is part of systemd <http://www.freedesktop.org/software/systemd/man/shutdown.html> and it is actually a link to it in CentOS 7, I've seen in the documentation <https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/System_Administrators_Guide/sect-Managing_Services_with_systemd-Power.html> that I can also use systemctl reboot But I can't find a way to provide a time specification in this latter form. What's the correct incantation? TIA, Carlos.
Hello Carlos, You can try the 'at' command to achieve the same result. Regards, -Mart?n On May 14, 2015 12:13 AM, "Carlos A.

It's a symlink, but systemctl knows to act differently when called as shutdown, and the traditional use still works. No need to hack around anything ? just use 'shutdown -r' as always. In Fedora at least, note that +1 is actually the _default_ ? I think that's true in EL7 as well but I don't have a system handy to check. See `man shutdown` for more. And `man systemd.time` for the time formats. -- Matthew Miller <mattdm at fedoraproject.org> Fedora Project Leader

I just wanted to know if there was a one-to-one mapping to the systemctl version. Thanks a lot, Carlos.
