.Fixes <https://issues.guix.gnu.org/52766>. Reported by Michael Rohleder <mike@rohleder.de>. * gnu/machine/ssh.scm (<machine-ssh-configuration>)[safety-checks?]: New field. (machine-check-file-system-availability): Return the empty list when 'safety-checks?' is false. (machine-check-initrd-modules): Likewise. * doc/guix.texi (Invoking guix deploy): Document it. Ludovic Courtès 2022-01-09machine: ssh: Open a single SSH session per machine....Previously, any call to 'managed-host-remote-eval' and similar would open a new SSH session to the host. With this change, an SSH session is opened once, cached, and then reused by all subsequent calls to 'machine-ssh-session'. * gnu/machine/ssh.scm (<machine-ssh-configuration>): Add 'this-machine-ssh-configuration'. [session]: Mark as thunked and change default value to an 'open-machine-ssh-session*' call. (open-machine-ssh-session, open-machine-ssh-session*): New procedures. (machine-ssh-session): Replace inline code by call to 'open-machine-ssh-session'. Ludovic Courtès 2021-06-03machine: ssh: Respect calling convention for monadic procedures....Fixes a regression introduced in 2885c3568edec35086f8feeae5b60259cbea407c. Reported by Mathieu Othacehe. * gnu/machine/ssh.scm (deploy-managed-host)[eval/error-handling]: Return two values in the standard case. Ludovic Courtès
