# This hook script prevents the user from pushing to Savannah if any of the new
# commits' OpenPGP signatures cannot be verified.

# Called by "git push" after it has checked the remote status, but before
# anything has been pushed.  If this script exits with a non-zero status nothing
# will be pushed.
#
# This hook is called with the following parameters:
#
# $1 -- Name of the remote to which the push is being done
# $2 -- URL to which the push is being done
#
# If pushing without using a named remote those arguments will be equal.
#
# Information about the commits which are being pushed is supplied as lines to
# the standard input in the form:
#
#   <local ref> <local sha1> <remote ref> <remote sha1>

Fixes &lt;http://issues.guix.gnu.org/44196&gt;

* 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.
(&lt;boot-parameters&gt;)[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.
* guix/scripts/system.scm (reinstall-bootloader): Use
boot-parameters-store-directory-prefix.
* test/boot-parameters.scm (%default-btrfs-subvolume,
%default-store-directory-prefix): New variables.
(%grub-boot-parameters): Use %default-store-directory-prefix.
(%default-operating-system): Use %default-btrfs-subvolume.
(test-boot-parameters): Add directory-prefix.
(test optional fields): Add test for directory-prefix.
(test os store-directory-prefix): New test.
