Vincent,

Thanks for the update!  I only recently (this year?) learnt of 
this readable alternative to /proc/cpuinfo.  Glad to hear it's 
seeing more action.

This was deliberate, for consistency:

  Wed Feb  5 2020 Todd Allen <todd.allen@etallen.com>
    * cpuid.c: Changed mp_synth fields to use '=' separator 
    instead of ':',
      like every other value.
    * cpuid.c: Changed processor serial number to use '=' 
    separator instead
      of ':', like every other value.

No:

  ~ λ guix refresh -l cpuid
  No dependents other than itself: cpuid@20200116

It's possible there's something out there calling cpuid from 
$PATH, but…

…honestly, you're overthinking it. :-)  There's a time to be 
cautious but bumping cpuid is probably not it.

Guix is exceptionally good at installing previous versions of 
packages for those who disagree.  I've pushed your patch as 
08fee94d0fd96ea2b40f9fec80dc3fa19e283019.

Note that git expects an empty line (newline) between the commit 
summary and the body of the message:

  gnu: cpuid: Update to 20200211.

  * gnu/packages/linux.scm (cpuid): Update to 20200211.

Thanks again,

T G-R
