Details

Description:

When having wpa_supplicant@wlp4s0.service enabled and there is no access point available, I have to wait 1.5 minutes to be able to login.

This seems like a very bad dependency configuration.

Additional info:
* package version(s)
* config and/or log files etc.

[16:45] wurzel:~% pacman -Q | grep -e systemd -e wpa_supp
lib32-systemd 230-1
libsystemd 230-5
systemd 230-5
systemd-sysvcompat 230-5
wpa_supplicant 1:2.5-3
wpa_supplicant_gui 2.5-3
[16:45] wurzel:~%


Steps to reproduce:

- create /etc/wpa_supplicant/wpa_supplicant-wlp4s0.conf with some essids
- enable wpa_supplicant@wlp4s0.service (or whatever your wifi device is)
- reboot without any accessible access point
- wait for 1.5 minutes
This task depends upon

This isn't because of wpa_supplicant, but probably because you have some other service which depends on network-wait-online.service (or network-online.target).

Nothing in wpa_supplicant@.service will produce the timeout that you describe, blocking bootup.

Hello Dave,

it doesn't seem to be the case:

[00:13:10] wurzel:~# systemctl --reverse list-dependencies network-wait-online.service
network-wait-online.service
[00:13:19] wurzel:~# systemctl --reverse list-dependencies network-online.target
network-online.target
[00:13:32] wurzel:~#


However, there are units depending on wpa_supplicant:

[00:14:51] wurzel:~# systemctl --reverse list-dependencies wpa_supplicant@wlp4s0.service
wpa_supplicant@wlp4s0.service
● └─multi-user.target
● └─graphical.target
[00:14:57] wurzel:~#

And this seems to confirm the behaviour that I see.

Alright, I've just seen that this might be some very, very old relict from an early systemd configuration.

I've removed the links from /etc/systemd/system/multi-user.target.wants/ and rerun systemctl enable and now it works correctly.

Sorry for the noise, please close the task.
