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)
vince@guixsd ~/guix-packages$ l

total 4.0K

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

It’s indeed harmless and fine.

Right, /gnu/store is meant to be read-only and manually modifying it
voids your warranty. :-)
https://www.gnu.org/software/guix/manual/html_node/The-Store.html
For this reason, /gnu/store is a read-only bind-mount on GuixSD.
That files in /gnu/store have group ‘guixbuild’ is innocuous.
I hope this clarifies things!
Ludo’.

The problem I saw here, was that a build *error* is ignored, even if
in this particular case it
is harmless. Or maybe chown is kind of special-cased when it is done
inside /gnu/store ?

The error is purposefully ignored here: upstream’s Makefile explicitly
marks it as can be ignored, using a hyphen (info "(make) Errors").
And indeed, it makes a lot of sense to ignore this error with Guix since
this operation is not permitted.
Hope this clarifies things,
Ludo’.

OK, thanks, that explains it, case closed...
