Yes, it's redundant.
Now I think the better way is just provide /etc/environment.
then `bash -l' would take ~/.bash_profile and ~/.profile.
We can have a default ~/.bash_profile like:
    source /etc/environment
    export PATH=$PATH:$HOME/.guix-profile/bin

And install skeletons only when needed by using:
    (operating-system
      (skeletons (list bash-profile)))

WDYT?

In fact, I'm confused about this even now :)

Sure, I'll try to write a patch, thanks for the direction.
