Is this really true?
Fedora-20 boots reasonably fast on my fairly old laptop (Thinkpad T61),
but I didn't notice any change when Fedora went over to systemd.
(I think my CentOS-6.5 desktop boots just as fast, if not faster.)
What exactly does systemd do differently that would speed up booting?
One trivial complaint I have with systemd is that I have to type more -
"sudo systemctl restart NetworkManager.service" against
"sudo service NetworkManager restart".
Not much difference, perhaps, but to me the necessity of adding ".service"
on my f20 i can do systemctl restart sshd
moreover you can do an alias like serviced="sudo systemctl"
(serviced because service is still used for /etc/init.d inhabitants)
but also you can do this:
sudo service sshd restart
Redirecting to /bin/systemctl restart sshd.service
also the reverse is possible:
sudo systemctl disable sys_basher.init.service
sys_basher.init.service is not a native service, redirecting to
/sbin/chkconfig.
Executing /sbin/chkconfig sys_basher.init off
shows that the developer just didn't think of the user's
convenience.
I know there are rare cases where one has to say something else,
but why not make the default to add ".service" if nothing is given?
Or perhaps TAB could complete it?
the autocomplete is working
And what (if anything) is the replacement for "chkconfig
--list"?
"systemctl --no-pager -a" for "all loaded
units/properties, including
dead/empty ones"
"systemctl --no-pager list-unit-files" for all units installed in system
for the current loaded units/sockets you have
systemctl list-units
systemctl list-sockets
as for the boot timings you have systemd-analyze and "systemd-analyze blame"
Overall check the man pages .. there are a lot of interesting things you
can do with systemd but it takes some time to get used to ...
i am still not comfortable with all the options of journalctl and i am
wondering how it will go when i will migrate my servers to centos 7..
