Udev service started but modules are not loaded.

[lidgnulinux]

I'm using LFS-based distro (I built it myself) and migrate from sysvinit to openrc. The system can boot properly but I notice a lot of modules aren't loaded (check it via lsmod). I have this problem before and it seems udev service is the culprit. I try to restart the service but no luck. Any clue?

• openrc version : 0.63.
• OS : LFS musl.
• udev : eudev.

Okay, tomorrow I'll try to rebuild eudev and see what happens.

Alright, I found the culprit, udev seems not started at all (/sbin/udevd won't run in the background). When I execute /etc/rc.d/rcS.d/S10udev (sysvinit service), all modules are loaded properly. Strange. I don't know why that happen.

please boot with rc_logger=yes, then gist/paste /var/log/rc.log

would be useful to also provide the S10udev service, as i'm not aware of where it comes from

Hello, sorry for the delay, it's my S10udev : https://bpa.st/ZBFVY and the openrc service exactly similar to gentoo.

The service's now started , yeay. I add a line under get_udevd_binary :

start_pre() {
(....)
	get_udevd_binary || return 1
	$command --daemon & #this is my addition.
(....)
}

Kinda wrong but it works.

Did you install an OpenRC-compatible init script for udev?

You will probably want to take Gentoo's init script from here.

Of course I have it, If I don't have it in the first place, it would be dumb to complain :3

[floppym]

Your rc log does not show the udev init script being started, so I wonder if you have configured it properly.

I give up! I wrote my own service file :

#!/sbin/openrc-run
# Copyright 1999-2013 Gentoo Foundation
# Distributed under the terms of the GNU General Public License v2

command="/sbin/udevd"
command_args="${udev_opts}"
command_background=yes
pidfile="/var/run/udev.pid"
description="udev manages device permissions and symbolic links in /dev"
extra_started_commands="reload"
description_reload="Reload the udev rules and databases"

depend() {
	need sysfs dev-mount
	before checkfs fsck
	keyword -containers
}

start() {
	${command} --daemon
}

stop() {
	ebegin "Stopping ${name:-$RC_SVCNAME}"
	udevadm control --exit ||
		start-stop-daemon --stop --exec "${command}" --pidfile "${pidfile}"
	eend $? "Failed to stop $RC_SVCNAME"
	[ $? -eq 0 ] && rm -f "${pidfile}" /run/udev/control
}

reload() {
	ebegin "reloading udev rules and databases"
	udevadm control --reload
	eend $?
}

i did not find anything wrong on rc.log, but by your gpm issue #968, this seems to be the same cause, so what we find there might fix the original udev script too
