Similar to <https://issues.guix.gnu.org/54469>, ‘home-bash-service-type’
doesn’t quote environment variables. For example, if you add this
service:
--8<---------------cut here---------------start------------->8---
(define bash-fancy-prompt-service
(simple-service 'bash-fancy-prompt
home-bash-service-type
(home-bash-extension
(environment-variables
'(("PS1" . "\\u@\\h \\wλ "))))))
--8<---------------cut here---------------end--------------->8---
… you end up with invalid shell code:
--8<---------------cut here---------------start------------->8---
$ tail -1 $(guix build
/gnu/store/maz98q1skyc7md2vknkg8ima3y2bq5yr-bash_profile.drv)
export PS1=\u@\h \wλ
--8<---------------cut here---------------end--------------->8---
