I had a small problem convincing aptitude to stop switching back to the old way any time that I wanted to install packages from security.debian.org [3]. After fixing that I have noticed no difference from the old way, whose name I have already forgotten. My hardware has a built in, intended, delay before start of boot, so I don't percieve that boot is faster. Maybe it is. I just can't see it in my particular set up. I am much more worried now about the world going nuclear before systemd gets a chance to prove its usefulness.+1000 sometimes people on this list get somewhat horny when discussing those things, which are really subjective in the end... they go onwith a mixture of tecno-steronic, 0.02$ philosophy which I can't stand:-(Peace to all, I hoperespect /raffaele Links: ------ [1] mailto:littdom@gmail.com [2] mailto:raffaele.morelli@gmail.com [3] http://security.debian.org [4] mailto:pecondon@mesanetworks.net
The speed you can gain by changing an application depends on more than one parameter. It depends on the software configuration of the system: switching from a KDE application to a GTK one ( on a GTK-based desktop ) will allow to notice resources gains. But also on the hardware you have: depending on the computer you have, running eclipse can start instantly ( at least, I guess so, I've never seen that ;) ), or starting even vim can take more than a second. Finally, it also depends on it's own configuration: keeping eclipse as an example, it will be obviously faster if you configure it to load less plug-ins.
Most of the time, it's stupid to say "my application will be faster than others which does the same, on all hardwares and softwares configurations". Except if you publish a fork in which you removed features, or fixed bugs. And even then, maybe the end user will not notice the speed improvement because he's computer is too fast for that.
Systemd, as every piece of software, also depends on those points. And speed is not the killer feature of this daemon, instead, it's easy to write configuration files ( and not, script files! ). For me, systemd is not a good choice. Because it does not fit with my objectives, and would only give me a very limited, if any, speed and maintenance gain: I like very minimalist systems, where things are started by hand if and when I really need them. So I do not have a lot of services. Plus, I am not a maintainer, so I do not have to maintain starting scripts ( but I need someone to do so instead of me, for now ;) ) and I think that it's easy enough to disable/enable a particular daemon, since we only need to change a file name and run #update-rc.d <script> defaults.
But, that's only my use. Normal users uses KDE or Gnome, with tons of potentially useful daemons started all the time ( cups, sane, network-manager, dbus, and for some programmers apache, php, DBMS... ) which are really heavy. For those, systemd will really be useful. And those daemons have dependencies on others, so it will help their maintainers to use systemd, too.
Note, I did not read the latest trolls. And I do not care if someone thinks I'm wrong. I have built my opinion on what I really need if systemd can help me with my own special needs long ago. And I think it is not a software built for peoples like me. I'm fine with that, and with Debian's default choice, as long as I can switch to others. I already manually explicitly ask debian to install lilo and not grub, no DE but instead a wm plus some specific tools, no "basic tools" but a hand-made selection of them. I can ask it to install a particular init system as well, I do not mind.
And people who are really angry about that Debian's maintainer's choice can just do the same, instead of flooding a mailing list dedicated to helping other people solving problems. That's what adults should do, btw. I'm becoming tired of all that useless noise around a subject which have been discussed so many times.
