I cloned your "channel.git" and checked out branch "wip-channel" but I
found nothing there that looks like a channel.  There are dotfiles, a
home and an os file, but that's not what a channel is.  A channel is a
bunch of guix modules (usually packages) that are meant to be shared.
It typically looks like guix or nonguix.

Dotfiles should not be in a channel because you don't want them to be in
your store.

If things are not meant to be shared, then there is no need to do a
channel.

Hope it helps,
Clément

P.S. Your parenthesis style doesn't help to read your code ;)
