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'.
Fixes a regression introduced in
2885c3568e.
Reported by Mathieu Othacehe.
* gnu/machine/ssh.scm (deploy-managed-host)[eval/error-handling]: Return
two values in the standard case.
Previously, '&inferior-exception' raised by 'upgrade-shepherd-services'
and co. would go through as-is, leaving users with an ugly backtrace.
* gnu/machine/ssh.scm (deploy-managed-host): Define
'eval/error-handling' and use it in lieu of EVAL as arguments to
'switch-to-system', 'upgrade-shepherd-services', and
'install-bootloader'.
This is a followup to 70ffa8af1e, which
did not really solve the problem.
* gnu/machine/ssh.scm (not-config?): New procedure.
(machine-boot-parameters): Use it as an argument to
'source-module-closure'.
* gnu/bootloader/grub.scm (grub-configuration-file): New parameter
store-crypto-devices.
[crypto-devices]: New helper function.
[builder]: Use crypto-devices.
* gnu/machine/ssh.scm (roll-back-managed-host): Use
boot-parameters-store-crypto-devices to provide its contents to the
bootloader configuration generation process.
* gnu/tests/install.scm (%encrypted-root-not-boot-os,
%encrypted-root-not-boot-os): New os declaration.
(%encrypted-root-not-boot-installation-script): New script, whose contents
were initially taken from %encrypted-root-installation-script.
(%test-encrypted-root-not-boot-os): New test.

operating-system-bootoader-crypto-devices and
boot-parameters-store-crypto-devices.

operating-system-bootloader-crypto-devices to provide its contents to
the bootloader configuration generation process.
(operating-system-boot-parameters): Add store-crypto-devices to the

variable.

* gnu/machine/ssh.scm (roll-back-managed-host): Use
boot-parameters-store-directory-prefix.
* gnu/system.scm (define-module): Export
boot-parameters-store-directory-prefix.
(<boot-parameters>)[store-directory-prefix]: New field. It is used to
generate the correct paths when /gnu/store is installed on a btrfs
subvolume whose name doesn't match the final runtime path, as the
bootloader doesn't have knowledge about the final mounting points.
[boot-parameters-store-directory-prefix]: New accessor.
(read-boot-parameters): Read directory-prefix from store field.
(operating-system-boot-parameters-file): Add directory-prefix to
store field.

from boot-parameters.
This is a follow-up of 755f365b02.
As (zlib) is autoloaded in (gnu build linux-modules), "guile-zlib" is needed
as an extension only when it is effectively used.
* gnu/installer.scm (installer-program): Remove "guile-zlib" from the extensions.
* gnu/machine/ssh.scm (machine-check-initrd-modules): Ditto.
* gnu/services.scm (activation-script): Ditto.

This commit adds support for GZIP compression for linux-libre kernel
modules. The initrd modules are kept uncompressed as the initrd is already
compressed as a whole.
The linux-libre kernel also supports XZ compression, but as Guix does not have
any available bindings for now, and the compression time is far more
significant, GZIP seems to be a better option.
* gnu/build/linux-modules.scm (modinfo-section-contents): Use
'call-with-gzip-input-port' to read from a module file using '.gz' extension,
(strip-extension): new procedure,

* gnu/system/image.scm (gcrypt-sqlite3&co): Ditto.
* gnu/system/linux-initrd.scm (flat-linux-module-directory): Add "guile-zlib"
to the extensions and make sure that the initrd only contains
uncompressed module files.
* gnu/system/shadow.scm (account-shepherd-service): Add "guile-zlib" to the
extensions.
* guix/profiles.scm (linux-module-database): Ditto.
This is a followup to 8e31736b0a.
* guix/scripts/system/reconfigure.scm (check-forward-update): Add
#:current-channels. Use it instead of OLD.
* gnu/services.scm (sexp->system-provenance): New procedure.

field.
Fixes <https://issues.guix.gnu.org/issue/41237>.
The UUID type information was lost when passing to the lower gexp code strata,
which led to not being able to recreate the UUID in the generated script.
This occurred for non-DCE type UUIDs such as that of a FAT file system.
A following commit will prevent the find-partition-by-uuid procedure from
entering a loop when its UUID argument is invalid.
Reported-by: Brice Waegeneire <brice@waegenei.re>

second argument.

instead of 'mlet' and 'machine-remote-eval'.

single gexp and pass it to 'machine-remote-eval'.
'this-machine' and 'this-machine-ssh-configuration' were useless given
that there are no thunked fields.
