No special permissions are needed for guix home to work. I'm using it on
a foregin distro and it works (still have some minor papercuts but
unrelated to this).

I think this is an issue due to the api changed for the
home-bash-service-type and the docs hasn't been updated. See this email
thread [0]. Try changing:

(bash-profile (list "export HISTFILE=$HOME/.bash_history"))

to

(bash-profile (list (plain-file "bash_profile" "export HISTFILE=$HOME/.bash_history")))

I hope that helps.
