I'd just like to add that if a user has guix installed for root but only
really keeps their user's guix up to date (I imagine a fairly common
situation), they're in for a weird situation when using sudo: a
bleeding-edge guix will complain about being outdated, since sudo (even
with -E) sets $USER, which is used to determine which file's timestamp
should be used for deciding whether the installed guix is outdated.
Basically, your shiny new guix warns you that someone else's dirty old guix
is old.
