This was helpful, but not enough.

Swapping them may have improved the likelihood of being able to retry,
but the issue is still there.  I uploaded as installer-dump-5f9f8dbe,
but it is pretty much the same as the previous dump.

Tomorrow, I will try to add an fsync call in between the two lines.

>   ./pre-inst-env guix system image -t iso9660 --label=Guix \
>     gnu/system/install.scm

Additionally, I had to do “GUIX_ALLOW_ME_TO_USE_PRIVATE_COMMIT=y
make update-guix-package”.  Or else the installer was using a Guix that
did not have the lines swapped.

Also before I did the GPG authorization dance (my x86 machine isn’t
worth getting my actual commiter GPG keys, so I make sure its dummy GPG
key is in the keyring branch, .guix-authorizations file, that
guix/channels.scm’s default guix channel points to the url
/home/florian/src/guix and to the commit with the new authorization).
Then I guix pulled.  So that building the installer succeeds.  I did
*not* use ./pre-inst-env.

Florian
