systemd: Yet Another Init Replacement

Viper_Scull · 2011-01-18 19:06:10

I've found these dependencies on a Debian page, just in case someone wants to add it to the wiki.

You also need a kernel with the following options enabled:
CONFIG_DEVTMPFS=y
CONFIG_CGROUPS=y
CONFIG_AUTOFS4_FS=[y|m]
CONFIG_IPV6=[y|m], optional, but highly recommended
CONFIG_FANOTIFY=y, optional, required for systemd readahed. availabe in Linux kernel >= 2.6.37-rcX. Needs to be enabled for the Debian Linux kernel (605636).

I checked out the config file and they are all met.

so thanks, i'm gonna get on it.

Ureadahead also requires a patched kernel to work properly, if you didn't know.

I didn't, thank you. I can see everything is well documented on the wiki.

I just commented about ureadahead because it worked quite well when i used ubuntu. But i'll try the readahead version from systemd.

Any idea whats wrong. fsck fails for ntfs partitions mounted with mtfs-3g as fsck.ntfs-3g does not exist (but systemd tries to load fsck.ntfs-3g instead of ntfsck). Thanks in advance.

I don't know how much KISS systemd is, but minit is pretty awesome. I'm really surprised no distribution has picked it up yet as their default init daemon:

You registered today, posted in a thread about one init system to recommend another.

Why?

Hi,
in the old rc.sysvinit script there are some lines which remove tempfiles in /tmp and few other locations. After switching to systemd my /tmp directory is full of stuff so probabily systemd has nothing similar. Is there a way to add that part of the script to systemd in some way?

I don't have ntfs here to test, but did you try to actually disable fsck on /etc/fstab for this partition or linking fsck.ntfs-3g to ntfsck?

This is still present in systemd. Look in /etc/tmpfiles.d/.

i have read the very long blog on 0pointer or whatsoever. as i understand, systemd starts daemons in parallel so that the boot time is shorter. what about the shutdown? how does systemd assure that all daemons are stopped properly? some daemon may stop correctly only if another daemon is actually running, not a fake socket or something. will systemd just blindly stop all the daemons in parallel?

falconindy · 2011-01-22 01:19:35

Systemd understands dependencies. Unit files have settings like 'After=network.target', meaning that a unit won't start until the network.target dependency has been satisfied. It's simple enough to just reverse this for shutdown.

that means the dependency of daemons in systemd is also a DAG?

falconindy · 2011-01-22 03:30:43

Directed acyclic graph? Yes, it's implemented using some amount of graph theory. I haven't looked at that section of the source in a long time.

systemd 17 released tonight.

yes. i thought the dependencies is treated as a DAG in sysvinit, only the sorting is conducted by users. i thought systemd may finally cope with cyclic dependency in daemons by parallel starting all of them. seems i was wrong.

and assuming the daemons array can form a DAG by their dependencies does not necessarily means that the init program should explicitly use that graph theory to cope with it. what the end users care is WHAT a program do, not how. and i think most people who thinks sysvinit is simple is talking about its easily describable and quite predictable behavior.

that's just my personal thought. i think systemd will get its place in big distributions, and the .target files it needs will be provided upstream gradually. anyway, Arch is bleeding edge, but i'd rather have those ubuntu guys be our guinea pigs.

Hi guys...I'm testing systemd v17 on my eeepc...I have some questions:

1) To booting the graphical session i have enabled the kdm@.service...It works, but there is another way to boot an X sessions? Such as adding a daemon in rc.conf despite enabling it in inittab...

2) When i boot (only with v17, before all worked) the eth0 and wlan0 devices are disabled...To have network manager working i have after every boot to:

# ifconfig eth0 up
# ifconfig wlan0 up
# systemctl restart networkmanager.service

3) I haven't found the {gdm,slim}.service, where have i to search them?

I take advantage of this post to congratulate with falconindy (and also Tom Gundersen) for the work done on the porting of systemd on Arch

I can see on the change list that Tom has removed rc-local.service.

Does that mean that rc.local is not supported anymore, or has it been moved to another location?

gdm and slim service files are part of systemd-arch-units, as is the NetworkManager service. Loading KDE as a daemon isn't even really supported in Arch. Boot with multi-user.target and run startx if you want an alternate way of starting X.

I assume the rest of your encrypted stuff works? There was a recently fixed bug with encrypted swap that should have made it into v17.

The question about KDM was only a curiosity So systemd doesn't support the launch of X session through startx, as sysV with:

x:5:once:/bin/su diego -l -c "/bin/bash --login -c startx >/dev/null 2>&1"

Last thing, nobody has the problem of the network interfaces that aren't enabled after the boot?

Viper_Scull · 2011-01-22 17:48:42

One more thing.

I've got util-linux-ng 2.18 installed, so when i try to install from aur util-linux-ng-git (cause wiki says 2.19 will have the needed feature) and replace the previous one, the terminal prints a warning telling i cannot do it because it's a dependency for several files (hal, mkinitcpio, etc, etc).

Do i need to remove all these packages, install systemd from git, and then reinstall them again?

You can force pacman to ignore the dependencies when removing a package by doing

pacman -Rd util-linux-ng

Then install util-linux-ng-git normally.

You can create a new service, I've used something like this:

[Unit]
Description=xinit for %i

[Service]
User=%i
ExecStart=/bin/bash --login -c startx

[Install]
WantedBy=graphical.target

Put it in /etc/systemd/system/xinit@.service and add a symbolic link to it from /etc/systemd/system/graphical.target.wants/xinit@diego.service.

This is still present in systemd. Look in /etc/tmpfiles.d/.

The systemd.conf contains this line

d /tmp 1777 root root 10d

According to the man page, everything older than 10 days should be deleted from /tmp, but my /tmp actually contains stuff much older than that. Maybe I have to enable some service?

First off, falconindy: THANK YOU. Awesome work here, systemd truly is something special in my opinion, a very practical and proper approach to solving the thrash that is system initialization.

I have some questions, I just switched from systemd-git to systemd from AUR to get v17 (was on some old git sync previously), so that is my version.

It seems like there is no net-auto-wireless unit, nor laptop-mode unit, however, from reading this thread I had thought that you were using the DAEMONS array to automatically start things from /etc/rc.d when they did not have a unit defined? Since right now I still have to manually /etc/rc.d/net-auto-wireless start if I want that service to start.

If I wanted to write units for this, would I fork your git repo and then create pull requests after the commits have been added (I've never pushed commits up so I'm a little new to this )

Also, how come there are packages initscripts-systemd-git and systemd-arch-units since both seem to provide units for systemd... shouldn't initscripts-systemd-git be merged into systemd-arch-units at some point?

Again, thank you! Hopefully I can submit some units to help out.

This is supposed to be triggered by arch-daemons.target. We may still have some bugs to hunt down...

initscripts-systemd provides more than just unit files. It's more like gluework to bind Arch's BSD'ish init config framework to systemd. On the other hand, systemd-arch-units is just a massive collection of unit files -- all of which should be getting distributed by either upstream, or by the individual packages that they belong to. If anything, I'd rather see systemd-arch-units disappear.
