It=E2=80=99s my attempt to help people not be as confused as I was. =
Maybe there
are better ways to achieve this? The two situations:

1. I followed the README instructions to build guix, and was quite =
confused
by the `localstatedir` business. I seem to be doing the most =
straightforward
thing, but have to dig through documentation/internet to continue since =
I
have no idea what/where localstatedir is. (I still don=E2=80=99t, and =
have been
doing quite fine without the knowledge.)

2. I ran guix pull && guix package -u. And afterwards, the guix =
development
environment was broken in an obscure way. Re-running guix environment =
guix
didn=E2=80=99t help. It turns out configure stores some full paths to =
core utilities,
such as

$ grep ^MKDIR_P config.status=20
MKDIR_P=3D'/gnu/store/lkrj6zifhk5dk888713dqyzfwk5bich0-profile/bin/mkdir =
-p=E2=80=99

To me it=E2=80=99s entirely unexpected that after a small OS update my =
dev environment
should break in this way.

Why would re-running the configure script be required after updating?

This section is about building Guix on a system that already has some
version of Guix to reduce the complexity of establishing a suitable
build environment.  I don=E2=80=99t think reconfiguring Guix System is rele=
vant
here.
