Confusion around the new `guix pull'

[Fis Trivial]

Hi guixs,

I have a few confusions around the new `guix pull' command. I tried to
re-read the documentation but didn't get around.

* Is it ok to remove /usr/local/bin/guix ?

Now the new guix command is resided in ~/.config/guix/current, is the
old one (linked from /root/.guix-profile/bin/guix manually) still
needed? I don't have any other users other than root and my current user
needs to use it.

Or, as a normal user(non-root), is there any different between using the
one linked at installation time (the one from root's profile) and the
one from $HOME/.config/guix/bin?



* What's the different for ~/.guix-profile/bin/guix and
  ~/.config/guix/current/bin/guix for root user account.

As a root user, there are two guix command now, as shown in the question
title.

        Which one should I use?

        What are the differences?

        Is there a right way to remove the duplication?


Or is there a section of documentation that explains the relationship
between the `guix' in /root/.guix-profile/bin and one in
/root/.config/guix/current/bin? I didn't found it, but if there is one,
please point me to it.


Thanks in advance.
