When a single channel is in use, ‘guix search’ understandable traverses
nothing but gnu/packages/*.scm:
--8<---------------cut here---------------start------------->8---
$ strace -o /tmp/,,s guix search sdfsdf
$ grep gnu/services /tmp/,,s
$ echo $?
1
--8<---------------cut here---------------end--------------->8---
But with multiple channels, all of the guile-module-union directory is
traversed, and that includes *everything*:

This was reported by bdju on #guix, who were getting the new SSH
password warning while running ‘guix search’.

I do not know what is the point of the strace command, but this file
contains a lot:

But no ’services’, indeed. The 3 first are expected since they used
somehow by files in ’gnu/packages/’. I am surprised by ’guix/scripts’
or ’guix/import’, the few I tried.
And I note a variation with the option ’-L’.

$ mkdir -p /tmp/foo
$ ls /tmp/foo/
$ strace -o /tmp/,,l guix search sdfsdf -L /tmp/foo

Well, I am not sure to understand… And last, the bug:
--8<---------------cut here---------------start------------->8---
$ strace -o /tmp/,,g guix search sdfsdf -L ~/src/guix/guix-past/modules
$ cat /tmp/,,g | grep 'gnu/services' | wc -l

$ ag services ~/src/guix/guix-past/
$ echo $?
1
$ ls -1 ~/src/guix/guix/gnu/services/*.scm | wc -l
50

All the best,
simon

The point :-) is to show that things that should definitely not be
loaded, such as gnu/services/*, are getting loaded when multiple
channels are in use.

What I have tried to show is that even with the default, «things that
should definitely not be loaded, such as guix/scripts/* or
guix/import/*» are getting loaded. And worse, adding an empty
“--load-path” adds burden. Multiple channels seems only one part of the
story. :-)
Cheers,
simon

False alarm! This was caused by a #:use-module (gnu) statement in one
of the Guix-Past modules, fixed here:
