Can't use feedkernel; doesn't allow running as root

[jscott0]

Hi,

I'm trying out the tentative solo-python package for Debian, version 0.0.26, and I can't use feedkernel.

$ solo key rng feedkernel
Entropy before: 0x3866
Traceback (most recent call last):

fcntl.ioctl(fh, RNDADDENTROPY, t)

It refuses to let me use it as root:

$ sudo solo key rng feedkernel
THIS COMMAND SHOULD NOT BE RUN AS ROOT!

Please install udev rules and run `solo` as regular user (without sudo).
For more information, see: https://docs.solokeys.io/solo/udev
Entropy before: 0x3911
Entropy after:  0x3915

I do have the udev rules though. The merge request #18 that introduced the feedkernel option says that it should just warn in recent versions, but 0.0.26 is the latest.

You can set the environment variable ALLOW_ROOT to suppress the warning if you know what you're doing.

$ sudo ALLOW_ROOT=1 solo key rng feedkernel

Here is what I get after trying to run solo key rng feedkernel:
