bug#25881: guix package --remove $PKG downloads and updates other packages

[dian_cecht]

Recently I had to remove duplicity from a profile because it doesn't
support hardlinks, and something very interesting happened:


=== start of output ===
guix package --remove duplicity
The following package will be removed:

in profile
=== end of output ===

I don' know why, but removing duplicity effectivly updated other
packages in the profile, which most certainly isn't related to 
uninstalling a package. I don't know if this is how things are meant to
be, but this behavior is entirely unexpected and makes no sense
whatsoever to me (especially since it has literally nothing to do with
uninstalling a program).

If this is the intended behavior, then I think some thoughts on whether
or not this violates the user's right to choose when and how they update
their system is needed.

As surprising as it may seem, this is expected: to build a profile, you
need Guile and a couple of other packages (such as Texinfo, to build the
‘dir’ file), which is why extra things are being downloaded/built.

I agree this is confusing, especially the way the UI shows it.  But it’s
an important feature.

IMO this doesn’t violate the user’s right to choose when they update
their system because it doesn’t update their system.

Thoughts?
