Re: Udev Rule Not Triggered

[Antwane Mason]

I'm honestly not sure what fixed the issue, but I am successfully able to
use the onlykey-cli without root privileges. I suspect the issue was my
method of testing whether a udev rule was being triggered actually was
interfering with it working. I used "udevadm test" and noticed two things.
First, was even when I was able to run onlykey-cli without root privileges,
running the test command did not show that the udev rule was triggered.
Second, each time the test command was performed, I had to restart the
computer before onlykey-cli would work again.

In addition to "udevadm test" being a potential cause of my issues, it is
unclear whether my system config changes also contributed to the solution.
Instead of creating a standalone udev rule service as I had originally,
I adapted the config from
https://lists.gnu.org/archive/html/help-guix/2018-05/msg00159.html and
modified the udev service type to include the udev rules for the onlykey. I
also imported the rules directly from github rather than manually
transcribing the rule as before.

I'm going to call it a day and try to do some exploration another day to
figure out the root cause. For now, I just wanted to say thank you,
Florian, for your help today. I hope this information can save someone else
some headaches in the future. If I find out the root cause, I'll be sure to
follow up here as well.
