during "guix package -i colordiff" I saw this error being reported:

cp colordiffrc /gnu/store/gc9vqsz0jzylcdsik0hmnghiff1kf3am-colordiff-1.0.16=
/etc/colordiffrc
chown root.root

colordiffrc
phase `install' succeeded after 0.1 seconds

But it looks like it is harmless (at least from the guix install PoV)

vince@guixsd ~/guix-packages$ l

This leaks the guixbuild group into /gnu/store, but it is not alone in
doing so...

If I try to do it manually afterwards, it obviously tell me the FS is R/O
