This is very nice.
As far as I know, the inferior interface is still "unstable", but this
would be a good start for a blog/cookbook article nonetheless! :)


Pierre,

I think something like this definitely should go in the cookbook 
regarding inferiors and the time-machine mechanism.


Let me know what I can do to help.

Hey all,

I am experimenting with the inferior system a little bit. I am

(operating-system

  ...

 (kernel (lookup-inferior-packages
  kernel-inferior-proc "linux-libre" "4.19.81"))

It took me some experimenting to come up with this, in that
experimenting the channel revision was built and cached. However, 
when
I run `guix system build config.scm` with the above code snippet, 
the

process just hangs on

Updating channel 'guix' from Git repository at
'https://git.savannah.gnu.org/git/guix.git'...

I am not sure how to proceed to achieve what I am hoping for. Any 
thoughts?

Update, I used guix time-machine to ensure that this specific build 
of

linux-libre 4.19.81 was available in the store, so now it is not
hanging:

Instead, it is telling me:

guix/gexp.scm:201:36: In procedure lookup-compiler:
In procedure struct_vtable: Wrong type argument in position 1
(expecting struct): (#)

Will keep investigating a way to do this.

Relevant bug issue.


I figured it out, nevermind!

Final solution:

(define kernel-inferior-channel
  ;; This is the old revision from which
  ;; we will obtain our desired kernel version.
  (list (channel
 (name 'guix)
 (url "https://git.savannah.gnu.org/git/guix.git;)
 (commit
  "fd41243c819635795f4e4bdef1e2823db5234e24"

(define linux-libre-4.19.81-inf
  (first
   (lookup-inferior-packages
(inferior-for-channels kernel-inferior-channel)
"linux-libre" "4.19.81")))

... in operating-system ...

 (kernel linux-libre-4.19.81-inf)
