There's also a rules dir under /lib/udev/rules.d/ Please locate the file that tries to set uinput and then determine to which package the file belongs with "qfile" (from app-portage/gentoolkit package).
Those are in /lib/udev/rules.d/30-kernel-compat.rules and seem to be Gentoo specific (see udev tarball).
> There's also a rules dir under /lib/udev/rules.d/ Ah, thanks. I found two files, which seems to belong to udev: root@moose:/root(10)# find /lib/udev -exec grep uinput {} \; -print KERNEL=="ts[0-9]*|uinput", MODE="0640" /lib/udev/rules.d/50-udev-default.rules KERNEL=="ts[0-9]*|uinput", NAME="input/%k" /lib/udev/rules.d/30-kernel-compat.rules root@moose:/root(11)# qfile -v 30-kernel-compat.rules 50-udev-default.rules sys-fs/udev-154 (/lib64/udev/rules.d/50-udev-default.rules) sys-fs/udev-154 (/lib64/udev/rules.d/30-kernel-compat.rules)
Like Rafał said definitely the fault of 30-kernel-compat.rules
I was guessing, what I could do and changed in /lib/udev/rules.d/30-kernel-compat.rules the line: KERNEL=="ts[0-9]*|uinput", NAME="input/%k" into KERNEL=="ts[0-9]*|uinput", SYMLINK+="input/%k" After that the kernel does not more complain. But does it make sense, what I did?
After upgrading udev to version 157 my change to /lib/udev/rules.d/30-kernel-compat.rules disappeared. Would it not be better to make the changes to /etc/udev/rules.d/60-thinkfinger.rules? It has now the contents: # SGS Thomson Microelectronics Fingerprint Reader ATTRS{idVendor}=="0483", ATTRS{idProduct}=="2016", SYMLINK+="input/thinkfinger-%k", MODE="0660", GROUP="fingerprint" # the also-needed uinput device KERNEL=="uinput", MODE="0660", GROUP="fingerprint" I tried to replace the last line by: KERNEL=="uinput", SYMLINK+="input/%k", MODE="0660", GROUP="fingerprint" But the error: udevd-work[1555]: kernel provided name 'uinput' and NAME 'input/uinput' disagree, please use SYMLINK+= ... did not vanish. I still get the additional error: udevd-work[1555]: device node /dev/input/uinput already exist, link to /dev/input/uinput' will not overwrite it. So I will again modify lib/udev/rules.d/30-kernel-compat.rules.
I'm getting the same error on udev-164. Can udev be patched to fix this rule with uinput until upstream gets around to fixing it? I'd like to note that I have uinput compiled into the kernel and not as a module.
Modifying /lib64/udev/rules.d/30-kernel-compat.rules also works for me as described above.
If you still have this bug. It is just udev complaining about the kernel not setting the path correctly itself. After an update to a recent kernel, udev should stop complaining. If there is a real need to use udev with older kernels and get rid of the warning we could patch it away.
I get the message: udevd-work[1598]: kernel provided name 'uinput' and NAME 'input/uinput' disagree, please use SYMLINK+= or change the kernel to provide the proper name also with the newest kernel: root@lynx:/root(3)# uname -a Linux lynx 2.6.38-gentoo #2 SMP Thu Mar 17 11:04:17 CET 2011 x86_64 Intel(R) Core(TM)2 Duo CPU T8300 @ 2.40GHz GenuineIntel GNU/Linux if I do not patch /lib/udev/rules.d/30-kernel-compat.rules. So I have to patch this file after each udev-update. Is there something wrong with my kernel config?

*** Bug 361609 has been marked as a duplicate of this bug. ***
still exists, sys-fs/udev-167 and gentoo-sources-2.6.38-r1. Please merge the fix. Thank you very much.
Ok, I did some searching, and as it seems udev upstream/kernel has dropped this "input/uinput" name and just changed to /dev/uinput. So we should just drop the rename rule for uinput. For compatibility we can make /dev/input/uinput a symlink.
Still not fixed: gentoo-sources-2.6.38-r4, udev-168-r1, uinput built-in
On a minor note: upstream has recently dropped many of those rules in git.
Fixed in udev-168-r2. But in udev-169 the rules are removed by upstream, as the kernel versions that needed it are no longer supported.
