Well, we intent to continue to make it possible to run udevd outside of
systemd. But that's about it. We will not polish that, or add new
features to that or anything.

OTOH we do polish behaviour of udev when used *within* systemd however,
and that's our primary focus.

And what we will certainly not do is compromise the uniform integration
into systemd for some cosmetic improvements for non-systemd systems.

(Yes, udev on non-systemd systems is in our eyes a dead end, in case you
haven't noticed it yet. I am looking forward to the day when we can drop
that support entirely.)

So, what is it going to take to convince Lennart that, contrary to what
he thinks, he actually isn't the only human on the planet?

I'd like to hear GregKH's take on this

I would love to see the day when I could have a udev-free system, and leave
UDEV/Poetterix to the lennartings...

Walter,

I'm confused about the xorg stuff in the WiKi. It mentions the evdev driver as
critical, but at the Notes at the bottom you say "evdev need udev to be
built". Can you clarify this?

Thanks

For some X11 configs (notably mine) it was necessary explicitly to
configure evdev in xorg.conf.  This used to work with, e.g., Gnome2.  At
a later stage, evdev suddenly required the udev USE flag to build.  :-(
This was taken account of in part of the web page, but not in the xorg
description (which is now wrong).

The change to evdev prompted me to stop using an mdev system, since I
anticipated not having enough time to keep it working.  (New job, and
such like).  The way certain developers are trying to force the world and
his dog to use a rigid Red Hat specified configuration, I might be
changing my time priorities.

I feared so. I read somewhere this is because xorg now asks udev about the
availability of evdev (writing from memory, can't find the reference). It
seems to me an artifice to force usage of udev. Are these people all in league
with each other?

Is it possible at all to drop udev and still use xorg? Are the old (i.e.,
pre-evdev) drivers still usable? Even if they are, I bet all future
developments will go the same way: force uniformity and submission.

The old kbd and mouse drivers for X still work without problem here.
Just set INPUT_DEVICES="keyboard mouse" in /etc/make.conf and rebuild
x11-base/xorg-drivers to get them.

Then you can configure them as ever in your xorg.conf.

  I'll have to edit the wiki.  The statement was probably correct when
originally posted, but recent builds of xf86-input-evdev require
>=x11-base/xorg-server-1.10 built with the udev flag.  *SOME* xorg input
device drivers require xf86-input-evdev and therefore udev.  I'm running
a few machines fine without evdev/udev, and xorg.conf for that matter,
under ICEWM.  xf86-input-evdev may also be required by fancy "desktop
environments".  Window managers like blackbox, fluxbox, FVWM, ICEWM, etc
can be dressed up to look rather fancy, and use a lot less resources
than GNOME/KDE/UNITY.

Hi Walter, can you expand on the LVM2 problem you mention on the MDEV
page and/or a link if there is one on the status?

I am building a new desktop (finally building as 64bit!) which will need
lvm2 and after trying gnome3 for a couple of months on my existing
machines, I have decided that its too unstable, too much of a resource
hog and such a major productivity killer so its time to abandon ship.
If I have to swim, I would like to use the opportunity to drop udev so I
can avoid that train wreck as well.

  I personally use ICEWM.  It does the job, and I get an autohiding
launchbar along the bottom.  Thinking about this has inspired me to
change my sig.  See below.

  I've never used lvm so I'm the last person to ask.  See
http://www.gentoo-wiki.info/Unionfs-linuxrc which mentions lvm2 under
mdev

  Alpine Linux is a server-oriented distro that uses mdev instead of
udev.  If anybody has gotten stuff running under mdev, it's them.  See
http://wiki.alpinelinux.org/wiki/Setting_up_a_software_raid1_array for
some hints.  The article looks a bit old, so I don't know if it'll work
for you now.

  If you get it running, please let me know, and/or update the wiki.
I'm going on a little trip later this month, after I get back, I might
just set up a dedicated test machine with all sorts of stuff like lvm2
on it.
