In a "headless" vm-image (sysi29.scm, attached), "font-dejavu" installed
by manifest (attached) into the "empty" default profile ...

'guix package -m manifest'

... appears in the emacs 'M-x menu-set-font' choice box. But it doesn't
appear with the same manifest installed in the "foo" profile ...

'guix package -p foo -m manifest'

... and run this way ...

source foo/etc/profile

emacs $@ --eval="(let ((guix-env \"foo\")) (when (and guix-env (require
(quote guix-emacs) nil t)) (guix-emacs-autoload-packages guix-env)))"

IIUC it shouldn't make a difference, but I also tried 'fc-cache -f'
before emacs to no effect.

Am I missing something?

TIA - George
