Hello!

I tried plugging in a USB drive on a GuixSD desktop system running from
the 'core-updates' branch and get this in dmesg:

[198220.121488] udevd[173]: RUN{builtin}: 'uaccess' unknown /gnu/store/cfs89vshgfzxr9rr311pf2y6cifyjq4l-udev-rules/lib/udev/rules.d/73-seat-late.rules:15
[198300.595192] udevd[173]: RUN{builtin}: 'uaccess' unknown /gnu/store/cfs89vshgfzxr9rr311pf2y6cifyjq4l-udev-rules/lib/udev/rules.d/73-seat-late.rules:15

And no new device node is created.

The offending file is here:
<https://github.com/elogind/elogind/blob/master/src/login/73-seat-late.rules.in>

I also found this: <https://github.com/gentoo/eudev/issues/145>

...but I'm not sure what to do about it. Should we just delete this
file, since it's seemingly unused on GuixSD?

I tried simply deleting it, but now *nothing* is registered when
plugging in a USB device. And I'm not sure why this problem occurs to
begin with, the changes since eudev 3.2.1 seem mostly harmless:

To be continued..

FWIW, I see the same error on my GuixSD system based on 'core-updates',
but for me it seems unrelated to USB drives.  The message is printed
quite frequently, even if I never plug in a USB drive, and plugging in
USB drives works perfectly for me.  The device nodes are automatically
created, and the filesystems are mounted by GNOME.

Thanks for checking. I found the problem: I happened to upgrade to 4.12
at the same time and neglected to enable this new option:

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=2c93e790e8253552227bf9b46a8d49dca3f71b06

And failed to notice that the uhci-hcd module consequently went
AWOL. I've learned to read my kernel configuration commits and
not automatically assume core-updates is broken ;-)

I guess now we're just waiting for Hydra to finish the x86* builds.
