mounting "my-home" to /home cannot work again.

If mount "my-root" to / only, my machine works well, when I mount "my-home" to /home, it cannot work well.
I cannot enter my guixsd again, "mounting-multi-part" has been broken?

These are generated by the kernel. There must be some stacktrace or
errors from guixsd missing somewhere, maybe when running guix system
reconfigure?

I don't see how an error in the guixsd configuration or a bug in
guixsd would cause the kernel to hang during boot, before entering the
initrd.

The recommended way of adding file-systems to an operating-system
definition according to the guix manual is:

(file-systems (cons* fs-root fs-home fs-backup1 fs-backup2 %base-file-systems))

Can you verify that the working setup kernel is the same one as the
non working setup kernel?

Possibly a relevant commit is 37203715805335131d18ac05ecb0367f222cd065.

HTH!

When I use (title 'device) instead of (title 'label), it works again, I don't understand the reason.

Re: Re: mounting "my-home" to /home cannot work again.

Hi!

I cannot reproduce the issue on current master, sorry!

make check-system TESTS="separate-store-os" would show if there's a
problem with multiple file-systems using labels.

If you want more help with your issue please come and visit us on IRC...

This file has:

(define fs-home
  (file-system
   (device "/dev/sda7")
   (title 'device)
   (mount-point "/home")
   (type "ext4")))

… which is correct.

If you previously had 'label instead of 'device here, the file system
could not be found at boot time because GuixSD was searching for a file
system with “/dev/sda7” as its *label*.

See
<https://www.gnu.org/software/guix/manual/html_node/File-Systems.html>
for the meaning of ‘title’.

HTH!

Assuming you have a default guixsd installation with no modifications,
you should be able to run `guix pull` to get the latest sources and
`guix reconfigure`.
