From 22bbdb5f794c9fe2f350f4295b8dcf93438ad011 Mon Sep 17 00:00:00 2001 From: Christopher Baines Date: Sun, 3 Sep 2017 11:47:58 +0100 Subject: vm: Add support for registering closures to make-iso9660-image. This mimics the functionality in the root-partition-initializer used in creating the QEMU image. This helps when trying to run guix system init from the generated ISO image. * gnu/build/vm.scm (make-iso9660-image): Add support for registering closures. --- gnu/build/vm.scm | 19 +++++++++++++++++-- 1 file changed, 17 insertions(+), 2 deletions(-) (limited to 'gnu/build') diff --git a/gnu/build/vm.scm b/gnu/build/vm.scm index 727494ad93..606257d8c3 100644 --- a/gnu/build/vm.scm +++ b/gnu/build/vm.scm @@ -366,12 +366,27 @@ (define (install-efi grub esp config-file) (error "failed to create GRUB EFI image")))) (define* (make-iso9660-image grub config-file os-drv target - #:key (volume-id "GuixSD_image") (volume-uuid #f)) + #:key (volume-id "GuixSD_image") (volume-uuid #f) + register-closures?
