bug#23970: colordiff glitch

[Vincent Legoll]

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
/gnu/store/gc9vqsz0jzylcdsik0hmnghiff1kf3am-colordiff-1.0.16/etc/colordiffrc
chown: invalid user: ‘root.root’
Makefile:24: recipe for target 'install' failed
make: [install] Error 1 (ignored)
chmod 644 
/gnu/store/gc9vqsz0jzylcdsik0hmnghiff1kf3am-colordiff-1.0.16/etc/colordiffrc
phase `install' succeeded after 0.1 seconds

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

address@hidden ~/guix-packages$ l
/gnu/store/gc9vqsz0jzylcdsik0hmnghiff1kf3am-colordiff-1.0.16/etc/
total 4.0K
-r--r--r-- 2 root guixbuild 963 Jan  1  1970 colordiffrc

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

address@hidden /tmp# chown root.root /gnu/store/*colordiff*/etc/*
chown: changing ownership of
