Don't forget ./pre-inst-env:

make && ./pre-inst-env guix system image -t iso9660 gnu/system/install.scm

Also, the installer won't use your locally modified guix.  IIUC,
it will use the 'guix' package, which is normally only used by a few services
like cuirass and guix-daemon, and for the initial installation.

It shouldn't be necessary to reinstall Guix System, I'd recommend sending a copy of
the locally-modified guix repo to your VM, build it, and reconfigure inside the VM
(./pre-inst-env guix system reconfigure ...) instead.

However, it should also be possible to modify the guix used by the installer, using the
procedure (current-guix) and and the macro modify-services, see gnu/tests/install.scm
for an example.
