Due to preparations for SeaGL and other matters, I'm afraid I won't have
much extra time until the end of this month. However, I've peeked at
the derivers, and I may have a hint for now.
The derivers' builders differ as follows:

Notably, they DO both seem to use the same store path for hello. The
only differing paths look like they were produced by profile hooks.
Perhaps this issue has something to do with profile hooks?

It=E2=80=99s not! Could you look at the derivers of these two profiles (use
=E2=80=98guix gc --derivers=E2=80=99) and see what differs?
Thanks,

Hi,
I've noticed that if I do the following...
guix package -p .guix-profile -i hello
guix package -p .guix-profile -i coreutils
guix package -p .guix-profile -r coreutils
...I get profile generations like the following:
.guix-profile-1-link -> /gnu/store/mbvwb1pv8ps0l39gil41g4zj3khx3r8p-profi=
le
.guix-profile-2-link -> /gnu/store/m6cwnnxcccnd8bga52jxn74vm67n7ry1-profi=
le
.guix-profile-3-link -> /gnu/store/qfpmx9rz7kxa8w8r2pz4vj8ilbi70dcp-profi=
le
However, the 1st and 3rd generations are practically the same:
=2D-8<---------------cut here---------------start------------->8---
$ diff -r /gnu/store/mbvwb1pv8ps0l39gil41g4zj3khx3r8p-profile /gnu/store/qf=
pmx9rz7kxa8w8r2pz4vj8ilbi70dcp-profile

p-profile}/bin${PATH:+:}$PATH"

Now, this isn't really a problem, since it isn't wasting space, and it
doesn't take long to build. It's more of a curiosity. Why is it that
profile generations 1 and 3 don't both point to the same profile in the
store? Is this expected behavior?
I wasn't sure what would happen when I tried this. I had guessed
(incorrectly) that generation 3 would point to the same profile that had
been built for generation 1, so I was a little surprised by this.
