[solved] Udev, Solid, systemd?

Hello,

I have installed archlinux recently to my friend's laptop and I forgot to add udev into DAEMONS array (there is only network, syslog, cron and dbus). Let me just say that inserting an USB soundcard works as intended. However, I did a full KDE installation there, so maybe it's solid related. When I started digging about udev, I got lost in udev's systemd integration.

Now, let me show quotes on udev from Beginner's guide:

Udev should be capable of detecting your hardware without problems and evdev (xf86-input-evdev) is the modern, hotplugging input driver for almost all devices so in most cases, installing input drivers is not needed. At this point, evdev has already been installed as a dependency of Xorg.

Ensure udev has loaded the driver, and that the driver has created a usable wireless kernel interface with /usr/sbin/iwconfig

Tip: Normally all needed modules are automatically loaded by udev, so you will rarely need to add something here. Only add modules that you know are missing.

Quotes from Installation guide: NO RESULTS.

So, in the Beginner's guide there is udev mentioned, but it's not actually said one should install it. I'm truely lost: why my friend's laptop detects all hardware even if there are only network, syslog, cron and dbus daemons? Do I need udev on my PC? What about systemd integration, have systemd already replaced old stuff on my friend's laptop? I just made generic installation using Beginner's guide.

AFAIK you don't have to list udev into the DAEMONS array. I don't have it either and nothing in the Beginner's Guide says you have to add it.

EDIT: Udev gets run during boot by something else, but I'm not knowledgeable enough to tell you what runs it.

initscripts runs udev unconditionally at boot, no need to do anything in particular to get it enabled.

Haha, just noticed I don't have udev either in DAEMONS. It starts anyway. Okay, I guess that solves my doubts.
