Since the recent ‘gnome-team’ merge, we get this message at boot time:

  udevd[87]: specified group 'sgx' unknown

Should we add ‘sgx’ to ‘%base-groups’?  (What is it for?)

This seems related to Intel's Software Guard eXtensions, or, as we in
the free world like to call them Security paper Generator eXtensions. 
As far as I'm aware, these ought to be disabled anyway, and we might
want to drop the offending lines.  According to [1], there's only two
of them anyway.

Cheers

Sounds good.  (My intuition would have been to create the ‘sgx’ group to
placate udev, but removing those lines may be even better.)

Can you look into it?

Thanks,

Given that patching the udev rules would require grafting eudev, but
more importantly, that the sgx extensions could well be used by Guix
System users on the right hardware (and having enabled the kernel option
for it), I've chosen the easy path which is to simply add a 'sgx' group
to %base-groups.

Pushed as commit 445d04f9d4e.

Closing!
