I could generate a new system, but upon booting it, I was dropped to a
Guile REPL.

So it doesn't seem to work.  How can I troubleshoot from there?

I used the following configuration for the EFI partition:

  (file-system
(title 'uuid)
(device (uuid "72E5-26A0" 'fat32))
(mount-point "/boot/efi")
(needed-for-boot? #t)
(type "vfat"))

Thanks for your work!

Kind regards,

Should I upgrade root user's guix too?

2017-09-22 Thread Attic Hermit

I use guix for using the softwares that Parabola GNU+Linux doesn't
provide. Everything works great, but I have a question on the upgrade of
guix itself.

I regularly do `guix pull && guix package -u` in my default user, but I
rarely do it in root user. I don't know if I'm right, but the guix build
users runs the guix of the version of root, so if I don't upgrade the
guix of root, that will stay on the old version for good. Therefore, the
guix of root should be upgraded as well, when the guix of the default
user is upgraded; Am I right?

If upgrading the root's guix is valid, then which guix should be
upgraded before? I usually upgrade non-root user's guix before
and then root's.

I couldn't find a related topic on the manual, so I'm little bit
confused.

This was reported at , and I suspect a
thread-safety issue.  However, syntax parameters are purely functional
AFAICS, so I fail to see why multithreading could be a problem.

Andy, any idea what could be causing this?

You mean the fix was insufficient?

The attached patch almost gets us there: it would allow you to write

  (uuid "-" 'fat32)

in your config.

However, there’s one thing I’d like to double-check with Danny, which is
the word order.  With this patch, I have:

  (fat32-uuid->string (string->fat32-uuid "aabb-ccdd"))
  $7 = "CCDD-AABB"

Danny: are you sure the most-significant 16-bit word comes last?

Ah, this is bad for me.  Now I need to redefine all those “#:emacs
,emacs” to “#:emacs ,emacs-checkout” as I guess.  Or I need to redefine
“emacs” variable instead of inherit it in “emacs-checkout”.
