Well, I do not think the compiler likes that.  From “guix repl”, it
raises the message:

;;; <unknown-location>: warning: possibly unbound variable `content'

and then ’bundle-package’ fails with:

ice-9/boot-9.scm:1685:16: In procedure raise-exception:
error: content: unbound variable

It is ’self-contained-tarball’ from (guix scripts pack), I guess.


Otherwise, it does the same thing as “guix pack foo”.

--8<---------------cut here---------------start------------->8---
scheme@(guix-user)> ,use(gnu packages base)
scheme@(guix-user)> (bundle-package hello)
$1 = "/gnu/store/riyxydg95yyczl6w4dv9j1rd9m1jbq1h-hello.tar.gz"
scheme@(guix-user)> ,q

$ guix pack hello
/gnu/store/0s6z9w6giwjh80ks4f3hwbhb1g9nhh8c-hello-tarball-pack.tar.gz

$ shasum                                                     \
    /gnu/store/riyxydg95yyczl6w4dv9j1rd9m1jbq1h-hello.tar.gz \
    /gnu/store/0s6z9w6giwjh80ks4f3hwbhb1g9nhh8c-hello-tarball-pack.tar.gz

--8<---------------cut here---------------end--------------->8---

And “guix package foo” can be done from the REPL using ’guix-pack’ from
(guix scripts pack):

--8<---------------cut here---------------start------------->8---
scheme@(guix-user)> ,use(guix scripts pack)
scheme@(guix-user)> (guix-pack "hello")
/gnu/store/0s6z9w6giwjh80ks4f3hwbhb1g9nhh8c-hello-tarball-pack.tar.gz
$1 = #t
--8<---------------cut here---------------end--------------->8---

Somehow, bundle-package is a simplified version without all the
“options“.  But hey, it is always cool to unwrap things and have a
better control. :-)  That’s why Guix is so cool! ;-)
