Hello!
I’m glad to report that this bug is fixed by
c90a4e8dcd6ac650392ffcc039273baf145aa3cc.
In these examples, you can see that all my channels are present, both in
a bare-bones ‘shell -CW’ (where bin/ is a direct symlink to the ‘guix
pull’ profile) and in ‘shell -CW coreutils’ (where bin/ fuses that of
coreutils and that of guix):
