Ah of course that is why it works for you.  I had deleted the locate
directory of the cache, so after `guix shell -CW -D guix` the `guix
locate ls` did not work, and did not work either once I had left the
container, because an empty database had been created in the cache from
within the container.  Without -CW it works fine.  It is a minor bug.

I’m nitpicking, but if relative file names are not meant to be
supported, could you change the doc/guix.texi at

+@example
+guix locate [@var{options}@dots{}] @var{file}@dots{}
+@end example
+
+@noindent
+... where @var{file} is the name of a file to search for.

to reflect that FILE must be the basename?  Because in other parts of
the doc, the term path is avoided and the term filename is used.  Now a
filename is only a basename all of a sudden.

Regards,
Florian
