Subject: [PATCH v2] machine/ssh: Refresh parameterization of %CURRENT-SYSTEM.
Date: Tue, 13 Feb 2024 11:50:02 +0100

The inversion actually didn't help.  For some reason, the effect of
PARAMETERIZE is lost.  With the patch below I can deploy to the
i686-linux laptop from my x86_64-linux machine again.

Subject: [PATCH v2] machine/ssh: Refresh parameterization of %CURRENT-SYSTEM.

When using "guix deploy" on an x86_64-linux machine to deploy a system to
i686-linux, DEPLOY-MANAGED-HOST would revert %CURRENT-SYSTEM to the host
system's value by the time it evaluated UPGRADE-SHEPHERD-SERVICES.  The
earlier PARAMETERIZE would no longer be effective.

* gnu/machine/ssh.scm (deploy-managed-host): Ensure that
UPGRADE-SHEPHERD-SERVICES is evaluated for the architecture of the target
machine.
