[EN] Survey on systemd Who uses it?

[piper]

I think a lot of customizations will be lost

I don't think /lib/lsb/init-functions would be editable anymore, I am sure there is a lot more that you won't be able to customize to "your" liking.

How is this going to effect the build process of siduction ?

Are tools provided to read these binary system logs whenever debugging some issue or in looking for errors to document in some bug report?

Yes, the command "systemd-journalctl" is the tool for listing the journal into a "most" window.  I haven't learned the options yet, but the basic command works as advertised.

"man systemd-journalctl" looks very complete.

Please note: My objections to systemd have nothing to do with the technical merits of either systemd or sysvinit.

Great, thanks. Also it might be useful to write a script akin to siduction-paste to highlight things of interest in the systemd logs and put them into a pastebin as part of troubleshooting or bug reporting

You can either look at man journalctl or read on it at: http://www.dsm.fordham.edu/cgi-bin/man-cgi.pl?topic=journalctl&ampsect=1v or read Lennarts blog about it on http://0pointer.de/blog/projects/journalctl.html

I have a laptop that I use mainly for experiments -- why it is still running I don't know.  :mrgreen:   It only took 5 minutes to install systemd, since I am already so experienced.  This one runs on an SSD, and it was already booting up pretty fast, but I was amazed at the boot on systemd -- between 9 and 10 seconds from grub to kdm, and  I have done nothing special to tweak it.

Don't forget to install the libpam-systemd and systemd-sysv packages, and to put systemd-sysv on hold. Here's the hardware:

Although I must admit I don't now very much what I'm doing but I belong to those who start and stop my laptop many times a day so I love a fast boot. I just took a chance and installed systemd, and yes it works and yes my laptop goes from grub to log in screen in 6 seconds

This is what I did: Installed systemd, libpam-systemd and systemd-sysv packages, and did put systemd-sysv on hold. Then rebooted.

Maybe or probably I will get into troubles on future d-u:s but that's then...

Edited: Hmm run into problem, the laptop will not shut down when using the menu at xfce, reboot works but not power off. So For now I have to do "poweroff" as root to be able to stop.

I have experimented with and am using systemd in Arch/Bridge and Gentoo.
It is forced on you in Arch as is in many Arch spins.
Gentoo my change was by choice just to give it a whirl.
 So, I like playing with systemd and the commands but as I use systemd for over a month I began to believe that the boot and process handling was superior to init.d
 Simple to add systemd with apt-get and Debian kernels work fine with systemd also.
Of course towo's kernels being specialized may need a tweak or two or three like
CONFIG_DEVTMPFS=y
CONFIG_CGROUPS=y

Then I as in Gentoo I just modified my grub.cfg

Code: [Select]

# $EDITOR /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="quiet init=/lib/systemd/systemd" <--- Change this line

# update-grub
  All seems to work fine but I have no problems with the current init scripting model. Plus, my testing has shown this Distro (Siduction) in particular boots and shuts down as aggressively as my systemd converts.

At the end of the Day for Me, I see no need for systemd. Maybe if it spit fire or something else interesting.
While I am interested to a small Degree my Vote as a user is systemd NO

Does anyone have a working journal with systemd? Even though I have libsystemd-journal0 installed, my /var/log is still what it used to be, no /journal.

If I call correctly, there is a simple one-time command to convert to journald logging. It may have been something as simple as creating the directory for it. I am sure there are good instructions on the Arch Wiki.

Edited: Hmm run into problem, the laptop will not shut down when using the menu at xfce, reboot works but not power off.

I also noticed what looks like a "hang" on restart or power off.  Just wait a minute or two (or three) -- eventually it always completes on my hardware.

@devil I am working on the permanent journal question -- no answer yet.


Edit:  I think I see the problem, down at the bottom of bug 691965.  They could mention that in the wiki ....    

[devil]

Found that by default the journal goes volatile to /run/log. You need to add a line to /etc/systemd/systemd-journald.conf like

Code: [Select]

Storage=persistent to make it go to /var/log/journal. Not very user friendly yet.

Looks like it's working to switch of now, yet not failed today and it's fast at switch off also.

That works correctly on my desktop system.  On a laptop and a netbook, it does not move the journal -- I still find it at /run/log/journal.  Strange ...
