I am trying to tweak my system's start time. Usually I go about it by using
systemd-analyze blame
Which gives me a list of stuff and how long it takes them to start. For this machine I don't need most of them, so it's a case of then
systemctl mask SERVICENAME
Or
systemctl disable SERVICENAME
But I am on a sysvinit system no and seeking alternatives for those commands.
Systemd Command ------------------------------- Sysvinit Command
systemctl start fooserv ------------------------ service fooserv start
systemctl stop fooserv ------------------------- service fooserv stop
systemctl restart fooserv ---------------------- service fooserv restart
systemctl reload fooserv ----------------------- service fooserv reload
systemctl condrestart fooserv ------------------ service fooserv condrestart
systemctl status fooserv ----------------------- service fooserv status
systemctl list-unit-files --type=service ------- ls /etc/rc.d/init.d/
systemctl enable fooserv ----------------------- chkconfig fooserv on
systemctl disable fooserv ---------------------- chkconfig fooserv off
systemctl is-enabled fooserv ------------------- chkconfig fooserv
systemctl list-unit-files --type=service ------- chkconfig --list
ls /etc/systemd/system/*.wants/fooserv.service - chkconfig fooserv --list
systemctl daemon-reload ------------------------ chkconfig fooserv --add
systemctl isolate multi-user.target ------------ telinit 3
systemctl halt --------------------------------- halt
systemctl poweroff ----------------------------- poweroff
systemctl reboot ------------------------------- reboot
systemctl suspend ------------------------------ pm-suspend
systemctl hibernate ---------------------------- pm-hibernate
journalctl -f ---------------------------------- tail -f /var/log/messages
systemd-analyze is a new command to check boot time
systemctl mask is a stronger version of systemctl disable. This will link these units to /dev/null, making it impossible to start them.
