Hi. I'm trying to build Xawtv in GuixSD to use my webcamera during
screencasts. I wrote package defintion for xawtv, it passes configuration
and build phases, but fails on install phase with error:

/gnu/store/6908gy3pws0ccys49ni98idwnicchlr2-coreutils-8.26/bin/install:
invalid user ‘root’

What do I need to do to avoid this error?


Here is xawtv.scm that I wrote:
