[SOLVED] [systemctl enable] how to modify the waiting time at startup

thomasbb · 12-27-2020, 10:53 AM

Some time ago, I enabled a dhcpcd service to have Internet access through my mobile by USB:

Code:

sudo enable dhcpcd@enp0s26f7u2.service

But now, I plan to use an ethernet link, without disabling the service. The problem is that at startup, "a start job is running"... Is there a way to reduce the waiting time from 1'30" to say 10"?

When I type systemctl cat dhcpcd @ enp0s26f7u2.service, I get:

Code:

$ systemctl cat dhcpcd@enp0s26f7u2.service
# /usr/lib/systemd/system/dhcpcd@.service
[Unit]
Description=dhcpcd on %I
Wants=network.target
Before=network.target
BindsTo=sys-subsystem-net-devices-%i.device
After=sys-subsystem-net-devices-%i.device

[Service]
Type=forking
PIDFile=/run/dhcpcd/%I.pid
ExecStart=/usr/bin/dhcpcd -q -w %I
ExecStop=/usr/bin/dhcpcd -x %I

[Install]
WantedBy=multi-user.target

is there a way to add a timer there?

Yes.
A 1 minute search got this result: https://unix.stackexchange.com/quest...-timeout-value
I hope it helps.
I must say I don't find this very elegant though; you should probably use some network managing tool, they exist in various colors, graphical or not. Some of them pretty close to systemd itself. Maybe netctl can do the job.

Sorry for not being too aware of the terminology... Apparently it calls drop-in files, here is what I did:

Code:

$ sudo systemctl edit dhcpcd@.service

and then the file has:

Code:

[Service]
ExecStart=/usr/bin/dhcpcd -q -w -t 10 %I

At next startup, I'll let you know how it went. Editing systemd "override" configuration files don't seem too dirty though?

Edit: the startup is much faster now... To the point I'm wondering if the service is waiting at all

Better to do it "the systemd way".

SOLVED?

Solved, thanks again
