systemd How I Converted My Arch to 100% Systemd or...

[V.T. Eric Layton]

Well, it was a way to waste 48 or so hours of my life, anyway.

[V.T. Eric Layton]

So, you wanna' go to systemd, huh Josh?

 

Well, read this thread to see how it's done.

 

Have fun!

Well I see this as a coming issue so I may as well jump through the hoops before being forced to.

[V.T. Eric Layton]

Those were my sentiments, also.

[securitybreach]

Well almost everything seemed to work fine except:

• the time was off but I think I fixed it (openntpd.service) and then I had to run ntp -s to update the time as it was off by more than 180 minutes
  
• I am having an issue getting netcfg to automatically connect upon bootup but it works with "netcfg mynetwork"
  
• lastly I am not able to display some characters correctly:
  

ââ comhack@Cerberus 01:08 PM

ââââ ~->

 

instead of:

╔═ comhack@Cerberus 01:13 PM

╚═══ ~/

 

I also had to manually start my daemons:

# systemctl start dbus.service

 

and to autostart:

# systemctl enable dbus.service

 

This was a bit of a pain as I had to do it for about 14 daemons.

[securitybreach]

Also, these are two services that are failing on startup but I have no clue on how to fix them:

 root@Cerberus comhack]# systemctl --failed
UNIT                      LOAD   ACTIVE SUB    JOB DESCRIPTION

ACTIVE = The high-level unit activation state, i.e. generalization of SUB.
SUB    = The low-level unit activation state, values depend on unit type.
JOB    = Pending job for the unit.

2 units listed. Pass --all to see inactive units, too.

[securitybreach]

I guess those are not the only issues:

[root@Cerberus comhack]# systemctl -a

171 units listed.

 

I removed the ones that started fine but here is the whole list if you want to look at it: http://pastebin.com/1TjwiXp4

 

I do not use a display manager so maybe I can just remove that one and I am not for sure about the plymouth ones so I will have do some reading.

[securitybreach]

BTW all of the service names are listed in /usr/lib/systemd/system/

[V.T. Eric Layton]

Well, you're making progress.

 

About the improper display of some characters... I read about that somewhere when I was upgrading to systemd. Can't remember the remedy at the moment, though.

 

Also, did you create the /etc/adjtime file that I mention above to correct the time errors?

[V.T. Eric Layton]

Oh, and are you booting an initrd? If so, did you remember to make a new one after converting to systemd?

[securitybreach]

Well the weird characters fixed themselves automatically?

I also fixed the pgl issue as it seemed the pgl-update.service automatically starts with the pgl.service. I am still getting the netcfg error though:

╔═ comhack@Cerberus 08:50 AM

SUB	= The low-level unit activation state, values depend on unit type.
JOB	= Pending job for the unit.

1 units listed. Pass --all to see inactive units, too.

[V.T. Eric Layton]

See posts above about time fix and initrd.

[securitybreach]

No I did not.

 

 

Oh, and are you booting an initrd? If so, did you remember to make a new one after converting to systemd?

 

I did not rebuild my initrd but I did do that when the update initially came through.

[securitybreach]

Also, did you create the /etc/adjtime file that I mention above to correct the time errors?

That fixed the time issue.

 

Thanks

 

I still do not know why display-manager.service tries to start as I do not use a display manager and I removed both kdm.service and gdm.service in case they were trying to start. Whenever I try to disable display-manager.service, it complains that it does not exist. I checked /usr/lib/systemd/system/ and it is not found. So why does it show up as an error when you list all of the services: systemctl --all:

 

[root@Cerberus comhack]# systemctl --all | grep display-manager
display-manager.service   error  inactive dead		  display-manager.service

 

but it does not show up as a failed service:

 

[root@Cerberus comhack]# systemctl --failed
UNIT					  LOAD   ACTIVE SUB	JOB DESCRIPTION
netcfg@multi-user.service loaded failed failed	 Netcfg networking service for profile multi-user

LOAD   = Reflects whether the unit definition was properly loaded.
ACTIVE = The high-level unit activation state, i.e. generalization of SUB.
SUB	= The low-level unit activation state, values depend on unit type.
JOB	= Pending job for the unit.

1 units listed. Pass --all to see inactive units, too.

 

As you can see it is not even found in /usr/lib/systemd/system/:

root@Cerberus comhack]# ls /usr/lib/systemd/system/ | grep display-manager
[root@Cerberus comhack]# 

[V.T. Eric Layton]

Rebooting to Arch. Stand by...

[securitybreach]

Ok, I added init=/bin/systemd to my grub kernel line.

[V.T. Eric Layton]

I get the same thing, apparently...

 

root@ericsbane05|Arch/home/vtel57:# systemctl --all | grep display-manager
display-manager.service   error  inactive dead		  display-manager.service

[V.T. Eric Layton]

Actually, I think the reason we're getting this error is because of the fact that we DON'T use a display manager.

[securitybreach]

Actually, I think the reason we're getting this error is because of the fact that we DON'T use a display manager.

 

Ok that makes sense but are you getting these errors too:

[root@Cerberus comhack]# systemctl --all | grep error
auditd.service            error  inactive dead          auditd.service
display-manager.service   error  inactive dead          display-manager.service
plymouth...t-wait.service error  inactive dead          plymouth-quit-wait.service
plymouth-start.service    error  inactive dead          plymouth-start.service
rc-local.service          error  inactive dead          rc-local.service

??

[securitybreach]

All of the above services are not listed in /usr/lib/systemd/system/

[V.T. Eric Layton]

Nope. The only FAIL notice I'm getting is the same one about kernel modules that I've been trying to resolve for a week or so. It's just a bug or config error because it doesn't affect the system at all. Everything is working.

 

root@ericsbane05|Arch/home/vtel57:# systemctl --failed
UNIT						 LOAD   ACTIVE SUB    JOB DESCRIPTION
systemd-modules-load.service loaded failed failed	 Load Kernel Modules

[securitybreach]

Well crap

 

OK well it looks like those are inactive processes anyway as they are not coming up as failed using: systemctl --failed

[securitybreach]

Reboot brb

[securitybreach]

Ok, now I now I fixed the issue with the boot messages clearing:

Q: How to avoid the console to be cleared after boot ?

 

A: Create a custom getty@tty1.service file

Copy /usr/lib/systemd/system/getty@.service to /etc/systemd/system/getty.target.wants/getty@tty1.service, and then edit the file:

• add --noclear to the ExecStart line after agetty
  
• switch TTYVTDisallocate to no

https://wiki.archlin..._after_boot_.3F

 

This really seems like it is complicating things a lot more.

[V.T. Eric Layton]

Alrighty... while looking for a resolution to display manager issue, I solved my Kernel Modules error issue.

 

In /usr/lib/systemd/system, there is this file:

Which led me to check those directories mentioned to see of there were actually any old modules files in any of them that are obsolete now. Well, there was. I had a sensors.conf in /etc/modules-load.d. I removed it and I no longer get the FAIL error now.

 

root@ericsbane05|Arch/home/vtel57:# systemctl --failed

LOAD   = Reflects whether the unit definition was properly loaded.
ACTIVE = The high-level unit activation state, i.e. generalization of SUB.
SUB    = The low-level unit activation state, values depend on unit type.
JOB    = Pending job for the unit.

0 units listed. Pass --all to see inactive units, too.

 

Now about the display manager thing. I get this in dmesg:

 

[    5.415300] systemd[1]: Cannot add dependency job for unit display-manager.service, ignoring: Unit display-manager.service failed to load: No such file or directory. See system logs and 'systemctl status display-manager.service' for details.

 

So...

 

root@ericsbane05|Arch/home/vtel57:# systemctl status display-manager.service
display-manager.service
     Loaded: error (Reason: No such file or directory)
     Active: inactive (dead)

 

Now what?

[securitybreach]

Yup I get the same error with display-manager.service. After I figured this out, I need to move on to my netcfg issues.

[amenditman]

I'm glad I'm waiting 'til you pros get this all figured out.

 

I could do it, but this would just kill the few brain cells and hair follicles I have left.

 

Good luck!

[securitybreach]

Well so far:

[root@Cerberus comhack]# systemctl status netcfg@multi-user.service
netcfg@multi-user.service - Netcfg networking service for profile multi-user
  Loaded: loaded (/usr/lib/systemd/system/netcfg@.service; enabled)
  Active: failed (Result: exit-code) since Mon, 30 Jul 2012 15:29:17 -0500; 6s ago
 Process: 2041 ExecStart=/usr/bin/netcfg check-iface %i (code=exited, status=1/FAILURE)
  CGroup: name=systemd:/system/netcfg@.service/multi-user

[V.T. Eric Layton]

That's why we get paid the BIG $$$.

 

So Josh... display-manager error fixed:

 

root@ericsbane05|Arch/home/vtel57:# systemctl --all | grep display-manager
display-manager.service   masked inactive dead		  display-manager.service

 

root@ericsbane05|Arch/home/vtel57:# systemctl status display-manager.service
display-manager.service
  Loaded: masked (/usr/lib/systemd/system/display-manager.service; masked)
  Active: inactive (dead)

 

I'm amazing sometimes...

 

The error in dmesg was stating that there was no such file or directory, so I made one.

 

In /usr/lib/systemd/system, create an empty file called "display-manager.service". Reboot. All better now.

[V.T. Eric Layton]

Did you enable netcfg.service? I can't remember reading above whether you did or not and I'm too lazy to look...

 

# systemctl enable netcfg.service

 

Also, some reading:

 

Since version 2.8.2 netcfg provides systemd unit files. The service files net-auto-wireless.service and net-auto-wired.service correspond to the initscripts daemons /etc/rc.d/net-auto-wireless and /etc/rc.d/net-auto-wired. To connect to multiple profiles at boot you can use netcfg.service which is equivalent to /etc/rc.d/net-profiles and starts all profiles specified in the NETWORKS array in /etc/conf.d/netcfg. These service files can be enabled and started with systemctl as usual.

Alternatively you can use the template service file netcfg@.service that allows you to connect to a single profile on boot without having to specify it in /etc/conf.d/netcfg. To specify the desired profile, create a corresponding symlink to /etc/systemd/system/multi-user.target.wants:

# ln -s /usr/lib/systemd/system/netcfg@.service /etc/systemd/system/multi-user.target.wants/netcfg@.service
