Correct.  It's only for (and on) the ‘live’ installer.

  After this /mnt/gnu/store is populated and the bootloader also 
  appears

to be installed.  However, this is not a usable system.


OK…  how exactly did you try to use it?


/mnt/{bin,etc,
home,run} are all empty (except for /mnt/etc/config.scm).  Where 
did I

go wrong?


What makes you think you did?  I've never seen these directories 
be populated by guix system init.


Did you try to boot it?  If so, please share the errors you got.

Kind regards,

"guix system init" from regular system fails

[li]

Hello,

  I am trying to prepare a new system on new drive from my current Guix
installation, i.e., the first way mentioned in (info "(guix)System
Images").  The documentation at (info "(guix)Invoking guix system)") is
sparse, so I followed those in (info "(guix)Manual Installation"), which
I have successfully done before a couple of times.

  I have made sure the partitions are mounted (/ and /boot/efi @ /mnt
and /mnt/boot/efi) and that that they are correctly configured in
/mnt/etc/config.scm.

  The only difference is that I did not run "herd start cow-store /mnt".
That service is only available when using the installer.  I also believe
that it is not necessary because the documentation says that

> This makes ‘/gnu/store’ copy-on-write, such that packages added to it
> during the installation phase are written to the target disk on ‘/mnt’
> rather than kept in memory.  This is necessary because the first phase

  In this case /gnu/store is not an in-memory file system, so I assume
this is not necessary.  But maybe something equivalent is necessary?

  "sudo guix system init /mnt/etc/config.scm /mnt" succeeds quickly
with output:

<...snip...>
/gnu/store/dhk4hrjpqfcph2alliwg18iiqwc3j86x-system
/gnu/store/q6b71455an8dl1hg8y859rkja22fxk4j-grub.cfg

initializing operating system under '/mnt/'...
copying to '/mnt'...
populating '/mnt'...
The following derivation will be built:
  /gnu/store/sjg10gcq9m88ad7q3znqxfc7qyq4aq8j-install-bootloader.scm.drv

building 
/gnu/store/sjg10gcq9m88ad7q3znqxfc7qyq4aq8j-install-bootloader.scm.drv...
guix system: bootloader successfully installed on /boot/efi


  After this /mnt/gnu/store is populated and the bootloader also appears
to be installed.  However, this is not a usable system. /mnt/{bin,etc,
home,run} are all empty (except for /mnt/etc/config.scm).  Where did I
go wrong?

  Thanks for your help!
