[SOLVED] Network service slowing down boot process

Hi,

When booting I got the a job stalling for 1min30

A start job is running for sys-subsystem-net-devices-net0.devices

when I checked the services I got only one fail message (not sure if related)

LOAD   ACTIVE SUB    DESCRIPTION
● systemd-vconsole-setup.service loaded failed failed Setup Virtual Console

My network is working perfectly on eth0 interface. I have no clue what this "net0" is.

When checking some more logs (journalctl -b | egrep "dhc")

systemd[1]: Dependency failed for dhcpcd on net0.
systemd[1]: dhcpcd@net0.service: Job dhcpcd@net0.service/start failed with result 'dependency'.

I found one message related but did not solve
https://www.reddit.com/r/archlinux/comm … ring_boot/

As a quick fix I have disabled it

systemctl disable dhcpcd@net0.service

Any idea how to check further what is causing that (which depency)?

Thanks

Re: [SOLVED] Network service slowing down boot process

If disabling it fixed the problem then it was only running because it was enabled. If it were a dependency, it would be run regardless.

Could be something you did and forgot about while following a tutorial, or maybe something stupid done by some piece of software during operation or installation. A bogus dhcpcd service can be enabled without any complaints from systemctl:

# systemctl enable dhcpcd@Fan
Created symlink /etc/systemd/system/multi-user.target.wants/dhcpcd@Fan.service → /usr/lib/systemd/system/dhcpcd@.service.

If you did it manually, there should be a record in the journal of the privilege escalation (sudo or PolicyKit). Beyond that I don't know how to tell where it came from.

I would guess this did come with a package update as I did not make any manual change when it started to appear.

Based on what you explain the "dependency" warning is confusing as disabling the service worked ....

Re: [SOLVED] Network service slowing down boot process

The service fails with a dependency warning because it depends on net0, which in your case doesn't exist.

When I said it wasn't a dependency issue, I meant that another service wasn't trying to start dhcpcd@net0 as a dependency.

Thanks,

That said in more than 2 years using the system, archlinux has been the most stable system I ever used :-)
